Amazon Elastic Caches?
Amazon Elastic Cache is a web service that manages the memory cache in the pall. In memory operation, the cache has a veritably important part and helps to reduce the cargo on the services, improves the performance and scalability on the database league by caching constantly used information.
Amazon RDS?
Amazon RDS (Relational Database Service) provides analogous access as that of MySQL, Oracle, or Microsoft SQL Garçon database machine. The same queries, operations, and tools can be used with Amazon RDS.
It automatically patches the database software and manages backups as per the stoner’s instruction. It also supports point-in-time recovery. There are no over-frontal investments needed, and we pay only for the coffers we use.
Hosting RDMS on EC2 Instances?
Amazon RDS allows druggies to install RDBMS (Relational Database Management System) of their choice like MySQL, Oracle, SQL Garçon, DB2, etc. on an EC2 case and can manage as needed.
Amazon EC2 uses Amazon EBS (Elastic Block Storage) analogous to the network-attached storehouses. All data and logs running on EC2 cases should be placed on Amazon EBS volumes, which will be available indeed if the database host fails.
Amazon EBS volumes automatically give redundancy within the vacuity zone, which increases the vacuity of simple disks. Further, if the volume isn't sufficient for our database's needs, volume can be added to increase the performance of our database.
Using Amazon RDS, the service provider manages the storehouse and we only concentrate on managing the data.
Auto Scaling?
The difference between AWS cloud armature and the traditional hosting model is that AWS can stoutly gauge the web operation line on-demand to handle changes in the business.
In the traditional hosting model, business soothsaying models are generally used to provision hosts ahead of projected business. In AWS, cases can be provisioned on the cover according to a set of triggers for spanning the line out and back. Amazon AutoScaling can produce capacity groups of waiters that can grow or shrink on demand.
