The purpose of this article is to introduce the readers to the more AWS services that organizations around the world are using and many more organization will be using in the future.
The services we will be talking about today are as follow;
AWS Snapshots
AWS LifeCycle Manager
AWS Cloud Trail
AWS Load Balancers
AWS Snapshots
AWS snapshots are nothing but the backup of the data in the cloud. The copy of the data gets stored on the Elastic Block Store (EBS) volume. It’s a virtual disk that allows the data of the EC2 instances to be stored in it. The reason we store the snapshot is to protect our data at all times. If something goes wrong we can always restore the data using the snapshots.
For example, if a user accidentally deleted a file or if the virtual disk malfunctions. The data can be restored. It is a crucial part of the disaster recovery strategy.
Analogy:
We can think of the snapshots as taking pictures of all the lego action figures. You take a picture and save the picture in a secure location, so if you ever lose or break a lego piece. You can get that piece and get it back to how it was originally, by referencing back to the picture. AWS snapshots are just like that, but they are for the virtual disks in the cloud.
LifeCycle Manager
Lifecycle manager feature helps clients manage the lifecycle of EC2 instances snapshots. The job of lifecycle manager is to automate the process of creating snapshots, copy them to another region, and discard the old snapshots if needed.
Lifecycle manager will keep all the snapshots organized. The clients can schedule the backup jobs, and define the retention period of the snapshots.
Cloud Trail
Cloud trail is like a detective for your cloud environment. The job of Cloud Trail is to help you keep track of what events are taking place in your Aws Account, and who is responsible for which events.
Everything that occurs in the AWS account, it could be creating an EC2 instance, deleting, creating a S3 bucket, creating users in IAM, or creating a VPC group; all the logs are found in cloud trail.
Analogy:
We have a security guard in the storage facility, the job of the security guard is to log every person who enters the facility and keep track of the reason they are at that particular facility. Security guard is making sure that the customers' belongings are safe and secure.
AWS Load Balancers
AWS tools which help distribute the incoming traffic across multiple resources, like VM or the containers. The load balancer's job is to improve the availability and reliability of the application, as well as the performance.
There are different types of load balancers offered by AWS classic load balancers, the application load balancers and the network load balancers each load balancer provides different functions.
Analogy:
Load balancer can be imagined as a traffic police officer directing the cars in different directions. The officer will direct some cars toward the different directions to get to their destination. This helps balance the flow of the traffic and prevent it from becoming a heavy traffic zone.
