For example: When an object is not accessed for more than 30 days it will be migrated to the infrequent access class. S3 Intelligent-Tiering: Consider it as an automated AI which monitors the object lifecycle in S3 and moves them to the appropriate class.S3 Standard: 99.99% availability, ideal for frequently accessed data.When you PUT or DELETE a current object, AWS provides Eventual consistency, it might take a while for the changes to be affected.(Read After Write Consistency) – PUTS to the new object When you create a new object, you will receive the latest object.The bucket name must be between 3 and 63 characters and can contain numbers, hyphens or periods.Bucket names are unique across all AWS Accounts!.Note: Only new objects will be replicated.

S3 data can be replicated across other regions, this is usually done for compliance.

To prevent accidental object deletion, enable versioning and MFA.

S3 Objects are saved in a container called “ Bucket“, consider Bucket as the root folder.

S3 Objects are replicated across multiple devices within a region!.

An object size could be from 0 to 5 TB.

Each object consists of a MetaData (created by Amazon) and Data (custom data).

EFS volume: are similar to EBS but with one major difference! One single EFS can be mounted on multiple EC2 instances.ĮFS data can be backed up in two options: You will be most likely be using General Purpose SSD for your webservers, only in rare use cases Provisioned IOPS SSDīonus Point: If the access pattern is random, SSD is best! HDD good for sequential access.ģ.

Use case: Critical application, hosting ELK, Applications that need very fast data access.

Use case: Big data, log processing, Log processing.

Use case: great for infrequent accessed, throughput-intensive workloads.

There are four types of EBS volumes: (use cases are important and the IOPS) EBS volume: This type of storage can be mounted on a single server. Data on EBS can persist beyond the EC2 lifecycle! Key point: Only one instance can be attached to a volume. Data is lost when the instance is restarted.Ģ. Very cheap and ideal for temporary storage. Instance store: Block storage volume attached to some EC2 instances. A solid understanding of AWS services is important: Storage types:ġ. It is more understanding what services you’re familiar with and which one would you pick.

In this section, AWS will question your knowledge on storage, decoupling systems so if one component fails it won’t cause major system downtime, how to design a multi-tier architecture, so systems can scale independently.

If you planning to get into a DevOps job building highly scalable architecture is important! By scalable I mean systems that can easily scale with no manual intervention. There are four main sections: Design Resilient Architecturesĭesign Secure Applications and ArchitecturesĪs an overview, the first three are very important.
