Advantages of AWS
Following are the pros of using AWS services:

Disadvantages of AWS
- If you need more immediate or intensive assistance, you’ll have to opt for paid support packages among 3 which are-
Developer: $29/month.
Business: Greater of $100 — or –(check the options).
Enterprise: Greater of $15,000 — or –(check the options ).
- Amazon Web Services may have some common cloud computing issues when you move to a cloud. For example, downtime, limited control, and backup protection.
- AWS sets default limits on resources which vary from region to region. These resources consist of images, volumes, and snapshots. You can launch the limited number of instance per area.
- Hardware-level changes happen to your application which may not offer the best performance and usage of your applications.
- Security Limitations: As security is one of the main features so AWS limits some of its features which cannot be changed at all are-
EC-2 classic- Maximum of 500 per instance and each Security Group can have a maximum of 100 permissions.
EC2-VPC- Up to 100 security groups per VPC.
Best practices of AWS
- You need to design for failure, but nothing will fail.
- It’s important to decouple all your components before using AWS services.
- You need to keep dynamic data closer to compute and static data closer to the user.
- It’s important to know security and performance tradeoffs.
- Pay for computing capacity by the hourly payment method.
- Make a habit of a one-time payment for each instance you want to reserve and to receive a significant discount on the hourly charge.
Acquisitions
Over time, AWS has acquired multiple organizations, increasing its focus on technologies it wants to further incorporate. These acquisitions don’t add to AWS, but rather enhance its core services. For example, AWS has acquired TSO Logic, Sqrrl and CloudEndure.
When it comes to AWS, you should not expect a perfect system with a simple setup where everything and everyone is waiting just for you. AWS is a complex infrastructure with its own rules and laws that you should respect and know. Once you are aware of them, your Cloud adventure will be much more comfortable than you ever imagined.
