Elastic Block Store (EBS)


Overview of EBS


AWS Elastic Block Store is a persistent block storage volume for use with EC2.


Each EBS volume is designed for 99.9999% availability & is automatically replicated within its availability zone.


EBS can be elastic in nature, thus supports the dynamic increase in capacity, performance and can change the instance type of live volumes.



AWS EC2 is regarded as a compute based service.


Compute generally refers to Memory & CPU

EBS and Portability


AWS Elastic Block Store is based on Network Attached Storage.


Since the storage is attached via the network, they can be easily detached as well hence providing the portability based feature.




Elastic Load Balancers (ELB)


Elastic Load Balancer allows us to distribute traffic to multiple EC2 instances thus avoiding a single point of failure.


ELB is capable of handling rapid changes in network traffic patterns.


Since it’s managed service, the client does not have to worry about the high availability related aspects.

Fundamentals of Cloud Computing Introduction to cloud computing: Cloud Computing is a model in which computing resource is available as a service. Three important characteristics of Cloud Computing : On-demand & self-serviced [ Any time launch without manual intervention ] A person can provision resources in the cloud whenever needed, without requiring any human interaction with a service provider. On-demand makes self-service with automation possible in a seeming less way. -Challenges with On-Demand Model: On-Demand does not always mean that you will be able to launch instances at any given point of time.   -Even a Cloud provider has limits, though it might be high, these limits are definitely reached. Elasticity.                                       [ Can scale up and down anytime ] Elasticity deals with adding and removing capacity, whenever it is needed in the environmen...
