EC2 is short for Amazon Elastic Compute Cloud

Amazon EC2 is like a special online service that gives you computer power. It's in the cloud, which means it's on the internet, not on your desk.

It's fast to get new computers with EC2. In the past, getting a new computer took a long time because you had to order it, and there were lots of cables to connect. But with EC2, you can have a new virtual computer in just a few minutes.

You can make your computer bigger or smaller whenever you need to. This is great because you only pay for what you use. In the old days, people used to buy big computers and plan for five years in advance. It cost a lot of money. But with EC2, you only pay for the computer power you actually use.

EC2 also helps software developers build strong and reliable programs. It gives them tools to make sure their programs work well, even when things go wrong.

EC2 Pricing Options

There are different ways to pay for Amazon EC2, and they have different benefits.

On Demand:

This is like paying for electricity. You pay for what you use by the hour or even by the second.

For Linux, you pay by the second, and for Windows, you pay by the hour.

On Demand is good if you want flexibility without any long-term commitment or upfront payment.

It's suitable for apps that have unpredictable workloads or if you're just testing things out.

Use it when you're not sure which type of instance you need.

Reserved:

Reserved means you make a deal with Amazon. You commit for 1 or 3 years.

When you reserve, you pay some money upfront, and in return, you get a big discount on the hourly charge.

It's great for apps with steady and predictable usage or when you need reserved capacity.

You can save more money if you pay all upfront for a 3-year deal.

There are different types of Reserved Instances:

Standard Reserved Instances: These give you the biggest discount, up to 75% off the On Demand price. Best for steady applications.

Convertible Reserved Instances: They offer a discount of up to 54% off On Demand. You can change the type of instance if needed, which is useful for changing workloads.

Scheduled Reserved Instances: You can reserve instances for specific times, like for a few hours every day or week, matching your schedule.

Each option has its own advantages, so you can choose the one that fits your needs and budget best.

Spot Instances:

Spot Instances let you bid for the price you want to pay for computing power. They are great if your applications can start and stop at flexible times.

These instances are useful for applications that can work when computing prices are very low.

If you suddenly need a lot of computing power, Spot Instances can help because they're good for urgent needs.

They cost less than On Demand instances but don't offer as big of a discount.

Spot Instances can help you save money and increase your application's performance by up to 10 times.

They stay running until you decide to stop them.

Dedicated Hosts:

A dedicated host is a physical server that is entirely for your use. It's like having your private server in the cloud.

You can use your existing software licenses for things like VMware, Oracle, or SQL Server on a dedicated host. This can save you money.

Dedicated hosts are used when you need to follow specific rules and reduce costs by using your own licenses.

You can buy them as reservations and get up to a 70% discount compared to On-Demand prices.
