Topics

EC2 – Elastic Compute CloudWeb service that provide compute capacity in the cloud

Traditional scenario- Long provision time- Underutilized resources- Risk of system failure during spikes

EC2 enables obtain virtual servers in the cloud.

Setting up environments requires only a few clicks

EC2 – Elastic Compute CloudProvides services like Auto Scaling, Load Balancing

Flexible for customers.Whether company is big or small, everyone can afford it.

EC2 – Elastic Compute CloudProvisioning Requires

Minimum Time

Minimum Effort

Launching a new instance

takes only minutes

Lets customer pay the amount they use

Helps customer get failure resilitent system

S3 – Simple Storage ServiceSimple web service interface for storing data (ranging from web applications to media files) in the cloud

Scalable service, starts from small and grow

Requires pay per use

The content can be sent to Amazon EC2 for computation, resizing, or other large scale analytics – without incurring any data transfer charges for moving the data between the services

S3’s Versioning capability provide protection for the stored data

Elastic Load BalancerAutomatically distributes incoming traffic across multiple EC2 instances

ELB ensures that only healthy Amazon EC2 instances receive traffic by detecting unhealthy instances and

rerouting traffic across the remaining healthy instances.

Helps customer get improved fault tolerant system

Auto ScalingEnables to scale EC2 capacity

During Spikes

Minimizes Cost

Customer sets conditionfor Auto Scaling Group

If CPU utilization > 70%increase 3 new instances

If CPU utilization < 10%decrease instances in same number

Auto ScalingCustomer can maintain a fixed number of EC2 instances

Condition set for Auto Scaling Group

Auto Scaling is enabled by Amazon Cloud Watch

Scales Up or Down using data provided by

Cloud Watch

Cloud WatchProvides monitoring for AWS cloud resources

CPU utilization

Data transfer

Storage

Basic monitoring collects and reports metrics for

Every 5 minutes

Detailed monitoring provides same metrics for Every 1 minute

Cloud Watch

Monitoring data retained for 2 weeks

Data can be retrieved programmatically or can be shown in graphs

Alarm can be set

- For help in troubleshoot

- Works as a trigger for Auto Scaling
