INTRODUCTION
The phrase “cloud computing” is used to describe several different approaches, but they all have the common goal of providing hosted services through the internet. The infrastructure, platform, and software as a service are the three main parts of any given cloud computing service (SaaS).
Public clouds and private clouds are two different kinds of cloud computing. Customers can buy services from a public cloud provider over the internet [1, 2, 3]. To provide hosted services to a limited audience, a network or data center might function as a “private cloud.” Access to the network and the kind of actions that may be performed with its resources are strictly controlled for these users. The purpose of cloud computing is to increase accessibility and scalability of IT resources and services by placing them in a central location accessible through the internet or another network.
To initiate a cloud computing paradigm, one needs both the proper software and hardware components. The term “cloud computing” is commonly used interchangeably with “utility computing” and “on-demand computing.”
Hundreds of thousands of companies in over 190 countries have made AWS their go-to cloud infrastructure platform. It has a solid reputation for dependability, scalability, and affordability.
CLOUD ARCHITECTURE
Cloud computing is used by companies of all sizes to store data and make it accessible to workers from any place in the company as long as they have an internet connection [4, 5, 6]. The architecture of cloud computing is a combination of ideas known as service-oriented and event-driven architectures [7, 8]. Fig. (1) explains the architecture of the cloud. The following are the two primary components that make up the architectural framework of the cloud:
Fig. (1)) Architecture for Cloud computation. Front end: The client works with the front end. It has the client-side APIs and applications needed to connect to cloud-based systems. Thin and fat clients, tablets, and mobile devices make up the front end, together with web servers (such as Chrome, Firefox, Internet Explorer, etc.).Back end: Service providers often make use of the back end. It controls every component needed to provide cloud computing services. Storage for vast quantities of data, firewalls, virtual machines, deployment methods, servers, traffic management systems, etc. are all part of the picture.TYPES OF CLOUD COMPUTING SERVICES
There are three main categories into which services provided by the cloud may be categorized [7]. An overview of various categories of cloud services is shown in Fig. (2).
Fig. (2)) Types of cloud services.Infrastructure as a Service (IaaS)
When we use infrastructure as a service, a cloud provider handles the nitty-gritty details on their behalf. These details include the management of servers, networks, virtualization, and data storage. Access to and management of the underlying infrastructure may be provided to the user in the form of either an application programming interface (API) or a control panel. User responsibility is restricted to the operating system, applications, and middleware, while provider supervision encompasses the hardware, networking, hard drives, data storage, and servers in addition to the management of any interruptions, repairs, or physical issues that may occur. This is the standard architecture for data storage services that are hosted in the cloud.
Platform as a Service (PaaS)
A model of cloud computing known as platform as a service (PaaS) is one in which the underlying infrastructure and application software are supplied and managed by a third-party provider. The user, on the other hand, is responsible for managing the applications that are deployed on top of that infrastructure as well as the data on which they rely. PaaS is primarily used by developers and programmers, and it gives these individuals access to a shared cloud platform for application development and management (an essential component of devops),
without requiring them to set up and maintain the necessary infrastructure on their own. PaaS is primarily used by developers and programmers.
Software as a Service (SaaS)
“Software as a service,” or SaaS refers to the practice of making cloud-based software applications available to end users. Applications that are provided as a software service are often accessible through a web browser on a personal computer or a mobile device [9]. The user just has to access the cloud applications via an interface or API; they take care of software updates, bug fixes, and other normal software maintenance on their behalf. As a result of the elimination of the need for software to be locally installed on each user's computer, SaaS paves the way for the establishment of additional channels for cooperative work.
Models for Cloud Computing Deployment
There are several different ways that cloud computing deployment may be carried out. They may be private, open to the public, or a combination of the two. Different Cloud deployment methods are shown here in Fig. (3).
Fig. (3)) Cloud deployment models. Private Cloud: After gaining an understanding of the advantages offered by the public cloud, it stands to reason that one would be curious to acquire knowledge about the capabilities offered by the private cloud. Businesses who want more control over their data and resources but don't want to break the bank may consider using private clouds instead of public ones. When this takes place, the department of information technology the user has, will be in charge of how it operates within the framework of the data center. An option would be to use a host that is located on the outside. The private cloud offers more opportunities for customizing services to the needs of particular companies than the public cloud does. Besides that, it is a great choice for mission-critical processes with dynamic parameters.Public Cloud: Everything that must be known about it may be gleaned just by looking at the name. It is openly available for usage by the entire public. Using deployment tactics that are based on the public cloud may be quite beneficial for organizations that have demands that are constantly shifting. It is also an excellent choice for companies that are not too concerned about the safety of their customers' personal information. This indicates that in order to take advantage of the networking, compute virtualization, and storage capabilities that are made available via the usage of the internet, users will be required to choose a cloud service provider. In addition to this, it is a great delivery method for teams that are working on both the development and testing of software. Because it is so easy to set up and deploy, it is an excellent choice for setting up demonstrations or test environments.Hybrid Cloud: As their name suggests, hybrid clouds are created by combining elements from two or more distinct kinds of cloud computing systems [10, 11]. Although the activities that are carried out by each model in a hybrid cloud are somewhat distinct from one another, the basic architecture that supports them all is the same [12, 13]. Also, assets can be added to this cloud computing system by both internal and external suppliers.The most sensitive information pertaining to a corporation should be stored in a private cloud, whereas information with a lower level of sensitivity might be preserved in a public cloud. One other common use of the hybrid cloud that's becoming more popular is cloud bursting. That is, let's say a company usually keeps an app on their own internal servers, but because demand is growing, they have to move it to the public cloud.
CLOUD COMPUTING'S CHARACTERISTICS AND BENEFITS
Cloud computing has several advantages, and organizations of all sizes may reap those advantages thanks to the current cloud computing architecture [7, 14, 15]. The advantages of using cloud computing are shown in Fig. (4). The following are just a few of the many advantages it provides:
Fig. (4)) Benefits of Cloud computation.Provisioning at one’s Leisure
Any user may quickly amass sufficient computing resources to complete almost any job. Users don't have to rely on IT staff to decide how to use computer resources like server time and network storage.
Elasticity
Businesses are able to swiftly scale up or down in response to changing demands placed on their information technology systems. This eliminates the need for major investments in regional infrastructure, which may or may not be operational at any given period in time [16]. For instance, the firm may speedily raise production in response to an increase in the demand for their goods.
Pay Per Use
Since every bit of computer power is quantified, customers pay only for what they really utilize.
Resilience of the Workload
Cloud service providers (also known as CSPs) often make use of redundant resources in order to ensure consistent data storage and the continued functioning of mission-critical workloads for their clients located in various regions of the globe.
The Capacity to Change Locations with Relative Ease
Cloud computing gives organizations the ability to transfer particular workloads across multiple cloud platforms on the fly, which not only helps them save money but also gives them access to cutting-edge developments.
The Capacity to Establish Connections with a Wide Variety of Different Networks
A cloud storage service allows users to store and retrieve data from any internet-connected computer.
Shared Use of Resources and Several Tenants
Users are able to use the same hardware and software via multi-tenancy, which does not compromise the users' own levels of privacy or security. By splitting up the capacity of a single pool of hardware, cloud service providers are able to potentially serve several customers at the same time. It is important for the cloud service provider to have a resource pool that is both sizable and adaptable enough to accommodate the requirements of a variety of customers at the same time.
These characteristics are responsible for a broad variety of benefits that may be realized by modern businesses, some of which are listed below:
Cost Control
When organizations employ cloud infrastructure, they save money not just on the initial purchase of essential gear but also on the cost of maintaining that hardware. This saves the companies a significant amount of money. They don't have to invest as much money in pricey hardware, infrastructure, and utilities, and they don't have to build as many enormous data centers to support their growing businesses, all of which contribute to a reduction in the amount of money spent on capital expenditures. In addition, businesses may decide to rely on the knowledge of the teams working for their cloud providers to manage the day-to-day operations of their cloud data centers rather than recruiting a large number of information technology employees. The costs that were incurred as a result of downtime have significantly decreased as a direct result of the adoption of cloud computing. Due to the infrequency of downtime, businesses don't need to use the resources of time and money to figure out how to handle it when it does occur. The advent of cloud computing has made this a realistic possibility.
Mobility of Data and Work
If a person chooses to keep their information in the cloud, they will be able to access it from any device so long as that device is connected to the internet. It is not necessary for users to own any external hard discs, flash devices, or CDs in order to access the data. It is possible for professionals to continue working from home with the assistance of their smartphones and other mobile devices, allowing them to avoid falling out of contact with their coworkers or customers. Users of the cloud computing service have quick and simple access to data that can be saved, retrieved, processed, and restored at any time. The fact that the cloud service provider takes care of all the necessary updates and upgrades is another advantage of using cloud computing.
Business Continuity and Disaster Recovery (BCDR)
Every company operating in the modern era has a significant concern over the possibility of data loss. Even if a user's main computer or mobile device (such as smartphone or laptop) is lost or destroyed, the data that is saved in the cloud may still be accessed by the user. Using cloud-based services, businesses have the ability to quickly recover their data in the event that there is a loss of power or a natural disaster. Even in the event that the company is subjected to disruptions or damage, it is possible for the data and workloads to still be accessible via the use of business continuity and disaster recovery (BCDR). This is one of the benefits of BCDR.
NEGATIVE ASPECTS OF CLOUD COMPUTING
Although there are many benefits to employing cloud services, IT professionals still confront a number of challenges when implementing and maintaining this technology.
Security in the Cloud
Concerns about the security of user data are among those that crop up most often in conversations about cloud computing. When utilizing cloud services, businesses run the risk of having our data compromised, having application programming interfaces attacked, of having their credentials leaked, and having authentication problems. It is also troublesome if the cloud provider does not give sufficient information about the manner in which and the location at which the sensitive data of the client is kept [17]. A comprehensive analysis of cloud configurations, business procedures, and legal frameworks is required to ensure the safety of data.
Cost Variability
When adopting pay-as-you-go subscription plans for cloud computing and scaling resources to meet shifting workload demands, it may be difficult to define and forecast potential expenditures due to the fact that these plans are based on a pay-as-you-go model. This is as a result of the particulars included inside these blueprints. Employing many cloud services that are all needed by a single cloud service will result in the same monthly cost to the employer. The costs associated with using the cloud have the tendency to be interdependent.
The Absence of Skill and Knowledge
As the demand for cloud-hosted workloads and data continues to rise, businesses are finding it increasingly difficult to keep up with the rising need for the tools and personnel required to design, install, and maintain cloud-hosted workloads and data because unexpected cloud expenses are making it more difficult for them to do so.
Governance of Information Technology
In this day and age of cloud computing, one of the possible challenges that IT governance may face is the lack of control that do-it-yourselfers have over the provisioning, de-provisioning, and management of infrastructure operations. The widespread use of cloud computing services is to blame for this unstable state of affairs. It might be challenging from the point of view of risk and security, compliance with IT standards, and the management of data quality.
Observance of Industrial Regulations
Data migration from on-premises to cloud storage could pose issues for firms wanting to comply with industry rules via a third-party service provider. Data and workloads need to be hosted in a manner that guarantees they are in line with all rules and regulations, and that also fosters good corporate governance.
Managing Various Cloud Providers
When deploying to several clouds, it's important to keep in mind that each cloud environment is unique, which might lead to disjointed attempts to solve broader cloud computing issues.
Efficiency when using the Cloud
When a business decides to use the services of a cloud provider, it gives up a great deal of control over the performance of the service, including latency. A breakdown of a firm's network or service provider may have a substantial effect on productivity and may interrupt regular business operations if the organization has not taken sufficient preparations for such contingencies.
Getting a Personal Cloud
When trying to develop, operate, and maintain private clouds, whether for independent reasons or as part of a hybrid cloud strategy, IT departments and staff confront a significant obstacle in the form of a formidable task.
The Transition to the Cloud
When it comes to the notoriously difficult process of migrating to the cloud, this is run for the course. It is not unusual for relocation initiatives to take substantially more time than intended and to cost significantly more than first expected. The process of transferring data from the cloud to a data center on the company's premises is one that is commonly neglected until it results in unanticipated expenses or hinders overall performance.
“Locking in” a Vendor
When switching cloud services, there are always issues. Technology incompatibilities, restrictions imposed by legal and regulatory bodies, and the prohibitive cost of moving large volumes of data all contribute to this problem.
CLOUD SERVICE PROVIDERS
Today's market is flooded with cloud computing service providers. The three largest public CSPs that have established themselves as market leaders are as follows: Amazon Web Services, Google Cloud Platform, and Microsoft's Azure.
There are a lot of factors to think about while looking for a cloud service provider. As a corporate customer, it is our duty to choose a service provider that can help us realize our vision in areas involving artificial intelligence and big data analytics.
Although most cloud services use a pay-as-you-go pricing model, there may be major price variations across providers. The location of the cloud provider's servers is also a significant factor if the data being kept there is very sensitive.
Consistency and security are, of course, two crucial concerns. The Service Level Agreement should specify the maximum percentage of downtime that the customer will allow for their operations. Having a firm grasp of the security measures and protocols used to safeguard crucial information is crucial when assessing various cloud service providers.
EVOLUTION OF AWS
AWS is quite prevalent in the modern age. But this success did not happen instantly; rather, it emerged in the early 2000s. Below, we've detailed some of the key points in the process's evolution. The same information is shown graphically in Fig. (5).
Fig. (5)) Evolution of AWS.The Formative Years (2000–2005)
AWS began operations not too long after the turn of the century. Since Amazon's e-commerce platform allows other vendors to create their own virtual stores, the business concluded that moving to a service-oriented architecture (SOA) would be the best way to increase their technical reach [18, 19, 20, 21, 22].
Matt Round offered various ideas at the time for how Amazon should speed up its software engineering, and the company implemented a number of those proposals. These included giving teams more freedom, adopting REST, and standardizing infrastructure. The implementation of continuous deployment and the removal of bureaucracy and decision-makers who acted as gatekeepers also contributed to this success. In addition, he advocated devoting more resources to software development at the expense of other activities [23]. To allow its engineering teams to devote more time to customer-facing innovation, Amazon opted to create a “common IT platform” to offload them from “undifferentiated heavy-lifting” like IT and infrastructure issues [24, 25]. To further accommodate irregular patterns of peak traffic, especially around the holidays, Amazon's Infrastructure team, led by Tom Killalea [26], Amazon's first CISO [27], has been running its data centers and associated services in a “quick, reliable, and economical” way.
In July 2002,[27] shortly after Colin Bryar assumed leadership of Amazon.com Web Services as its chief executive officer, the company released its initial set of web services, making the Amazon platform available to all developers.
By 2004, it has been used to develop more than a hundred separate software programs [28, 29]. Amazon was taken aback by the level of cooperation from developers, but it quickly became clear that programmers were “hungry for more.” In spite of this, Amazon seemed taken a back.
[24] They released a collection of basic infrastructure primitives as part of the “Internet Operating System” to facilitate the quick deployment of software applications [18, 19, 20, 22, 30, 31]. Early components of Amazon's first set of infrastructure components include databases, storage space, and processing power, all of which date back to the autumn of 2003 [18, 20, 22, 25]. AWS was founded because of Amazon's hasty desire to “create, develop, reinvent, rebuild, begin again, and do it again,” an ambition that spawned “2 teams” and distributed systems. Brewster Kahle, whose company, Alexa Internet, was bought by Amazon in 1999, claims that the technology he developed at the company's early stage helped Amazon overcome massive data issues and eventually establish the technologies that underlie AWS.
By the year's end of 2003, they had written a document outlining a proposed architecture for Amazon's retail computing that was entirely standardized and automated, significantly used web services for things like storage, and built upon existing work inside the company. This piece would eventually become important in putting EC2 in place. After a few more lines, they suggested charging consumers for the option to use virtual servers in order to recoup some of the company's recent capital expenditures [32]. So, after that, a team in Cape Town, South Africa, established the Amazon EC2 service [33].
Amazon Web Services released its Simple Queue Service (SQS) not long after launching its first public infrastructure service in November 2004.
First Generation (2006–2010)
Amazon S3 [34], AWS's cloud storage service, launched on March 14, 2006, while Elastic Compute Cloud (EC2), another AWS service, launched in August of the same year [35]. Amazon Simple Storage Service (S3) was proclaimed the best in the industry by AWS's vice president in 2006 “allows developers to concentrate on making rather than considering issues like where data should be stored, if it will be safe and secure, if it will be available when it is needed, if routine maintenance will cost too much, or if there is enough storage space. Amazon S3 is not only a repository for information; it also encourages creative use of that information.” The Pi Corporation, founded by one of its original members, was the first non-Amazon business to use the EC2 beta [22]. Microsoft was also an early enterprise user of EC2. [36] A claim was made by SmugMug, an early adopter of Amazon Web Services, that they saved almost US$400,000 in storage expenditures by adopting S3 at the end of the year [37]. According to Vogels, S3 had more than 300 microservices by 2022, up from 8 in the original 2006 deployment.
[38] Starting in September 2007, American entrepreneurs and software engineers who had used AWS services like S3 and EC2 to get their businesses off the ground were eligible to win a share of $100,000 in prizes at Amazon Web Services' (AWS) annual Start-Up Challenge.
Growing Generation (2010-2015)
By November of that year (2010), it was expected that all of Amazon.com's retail sites will have relocated to AWS [39]. Before 2012, when it was decided that AWS was no longer a separate entity, the company's financial statements did not break out AWS's revenue from Amazon.com's. In that year, experts predicted that Amazon Web Services (AWS) would generate more than $1.5 billion in revenue [39].
Amazon Web Services launched a certification program me for computer engineers on April 30, 2013 [40] as part of its mission to increase familiarity with cloud computing. The Activate initiative for startups was introduced in the same year, in October. Startups may take use of free AWS credits, third-party integrations, and consultations with AWS experts via this initiative, which is designed to help them grow their businesses internationally [41].
To better aid businesses that operate on AWS, AWS launched its partner network in 2014 under the moniker APN (AWS Partner Network) with the goals of fostering close collaboration and sharing industry best practices in order to help businesses that operate on AWS grow and scale their commercial success [42, 43].
According to Amazon, AWS turned a profit for the first time in the first quarter of 2015, with revenues of $1.57 billion and operating profitability of $265 million. Incredible returns compared to initial projections: Founder and CEO Jeff Bezos called it a “rapidly growing” $5 billion enterprise [44]. Amazon.com reported $521 million in AWS operational income and 25% operating margins in its quarterly results report for the third quarter, which was published in October. AWS produced $2.1 billion in revenue during the third quarter of 2015, up 78% year-over-year from the $1.17 billion it made during the same period in 2014 [45]. For the fourth quarter of 2015, AWS sector sales surged by 69.5% year over year to $2.4B, leading to an operating profit of 28.5% and an annual run rate of $9.6B. Customers of Amazon Web Services (AWS) adopted the cloud computing platform at a pace 10 times greater than the adoption of the following 14 providers in 2015, as reported by Gartner [45].
Market Leader (After 2016)
With a 64% increase in sales and net profit in Q1 2016, AWS overtook Amazon's retail division in North America in terms of profitability for the first time [46]. Stock in Amazon rose 42% due to the company's increased profitability, with 56% of net income coming from AWS [47].In 2017, AWS earned $17.46 billion in revenue [47]. As of the year 2020, total sales had reached $46 billion [48]. Back in January of this year, [49], Amazon launched its AWS auto scaling service [50]. In November 2018, AWS released ARM cores that were specifically tailored to the needs of its server infrastructure [51]. Amazon Web Services (AWS) is also working diligently on ground stations that will be able to interact with customer satellites by the end of 2018.[52] The Amazon Web Services (AWS) division grew by 37% last year and now contributes 12% of Amazon's total revenue (up from 11 percent in 2018).[53] In April, the data for the first quarter of 2021 in the cloud computing sector were made public, and they showed that Amazon Web Services was responsible for 32 percent of the industry's $41.8 billion in sales.GLOBAL INFRASTRUCTURE OF AWS
Multiple data centers across the globe serve as hosts for Amazon Elastic Compute Cloud. They comprise AWS Outposts, Local Zones, Availability Zones, Wavelength Zones, and Regions. From a geographic standpoint, each Territory is divided into its own distinct area. Availability Zones within each Region are dotted with dispersed outposts.
Local Zones allow for the distribution of data center resources like processing power and data storage to several locations that are physically closer to the end users. It is possible that these locations will be dispersed across a larger region.
With AWS Outposts, on-premises, co-location, and data center facilities may use AWS's infrastructure and services without having to move their operations to the cloud.
The usage of Wavelength Zones in the development of ultra-low latency applications would benefit both 5G infrastructure and end users. Wavelength is helping telecommunications firms by deploying edge computing and storage services that meet AWS specifications at the edge of 5G networks.
AWS's data centers are cutting-edge facilities with extensive failsafes. Although failures that affect the availability of instances in the same area are uncommon, they do occur. All of the instances would be unreachable if they were hosted in a single location and that location had a failure. As shown in Fig. (6), there is a connection between the regional, Availability Zone, and data center layers of the overall architecture.
Regions
Every Amazon EC2 Region should be completely separate from every other. Since this is the case, the highest levels of fault tolerance and stability are attained. Only materials relevant to the Region of interest will be shown during this review. Because we don't link regions with each other and because we don't automatically replicate resources across areas, this is the case. Furthermore, the climate and ecology of each area vary.
An AMI built in the same area must be used when launching an instance. AMIs may be moved from one Region to another by making a copy and deploying it there. Any information sent from one Region to another will incur a fee.
Available Regions
By default, each AWS account comes with access to numerous Regions, allowing us to launch Amazon EC2 instances in a variety of locations across the world. There are a number of reasons why setting up a shop in Europe might be advantageous to the company, including the ability to better serve European consumers and the certainty that they will be in complete compliance with all local legislation.
In order to access the AWS GovCloud (US-West) Region, a user must first have an account in the AWS GovCloud (US-East) Region. Users with an Amazon AWS (China) account are restricted to the Beijing and Ningxia Regions for their cloud computing needs.
Regions and Endpoints
When utilizing the instance through the API or command line interface, the regional endpoint must be supplied.
This data is accessible using the Amazon EC2 command line tool or the graphical user interface. Users may use the system to get knowledge about their local areas.
