Choosing the Right Amazon EC2 Instance

EC2 instance types are optimized for different use cases and come in multiple sizes. This allows you to optimally scale resources to your workload requirements.AWS uses Intel® Xeon® processors for EC2 instances, providing customers with high performance and value.Consider the following when choosing your instances: Core count, memory size, storage size and type, network performance, and CPU technologies.Hurry Up and Go Idle - A larger compute instance can save you time and money, therefore paying more per hour for a shorter amount of time can be less expensive.


Intel® Processor Technologies

Intel® AVX – Get dramatically better performance for highly parallel HPC workloads such as life science engineering, data mining, financial analysis, or other technical computing applications. AVX also enhances image, video, and audio processing.Intel® AES-NI – Enhance your security with these new encryption instructions that reduce the performance penalty associated with encrypting/decrypting data. Intel® Turbo Boost Technology – Get more computing power when you need it with performance that adapts to spikes in your workload with Intel® Turbo Boost Technology 2.0


Instance Metadata & User Data

Instance Metadata:Is data about your instance.Can be used to configure or manage a running instance.

Instance User Data:Can be passed to the instance at launch.Can be used to perform common automated configuration tasks.Runs scripts after the instance starts.


Adding User Data

You can specify user data when launching an instance.User data can be:Ø Linux script – executed by cloud-initØ Windows batch or PowerShell scripts – executed by EC2Config service

User data scripts run once per instance-id by default.


Amazon EC2 Purchasing Options

DB Instances

DB Instances are the basic building blocks of Amazon RDS.They are an isolated database environment in the cloud.They can contain multiple user-created databases.


How Amazon RDS Backups Work

Automatic Backups:Ø Restore your database to a point in time.

Ø Are enabled by default.Ø Let you choose a retention period up to 35 days.

Manual Snapshots:Ø Let you build a new database instance from a snapshot.

Ø Are initiated by the user.Ø Persist until the user deletes them.

Ø Are stored in Amazon S3.


Multi-AZ RDS Deployment

With Multi-AZ operation, your database is synchronously replicated to another AZ in the same AWS Region.Failover automatically occurs to the standby in case of master database failure.Planned maintenance is applied first to standby databases.
