Elastic Computer Cloud

Introduction: Through cloud computing, Amazon has supported the use of the Internet and a central remote server to maintain data and applications, and created an unobtrusive ubiquitous environment for connectivity and ease of use. Amazon provides two options for hosting applications and databases. Amazon EC 2 with elastic block storage can run MySQL database server with Elastic Compute Cloud, a service provider infrastructure with Elastic Block Storage (EBS). . At the same time, another option called Amazon Relational Database Service (RDS) is an extensible relational database with high availability in the cloud.

EC 2 stands for Elastic Compute Cloud - Service and provides scalable computing capacity in the Amazon Web Services (AWS) cloud. With EC 2, you can start virtual servers, set up network and security on them, attach storage, public IP addresses, or associated domain names. Using EC 2 reduces the need to predict traffic because computing resources can be scaled down or down based on changes in demand and popularity peaks. Once instances are started, they are associated with one or more security groups. The virtual firewall applies a set of rules to control traffic to and from the instance. AMI (Amazon Machine Image) is a template that contains software configuration such as operating system and software package. With AMI you can start an instance containing a copy of AMI running as a virtual server in the AWS cloud.

The concept of cloud computing is that computer hardware is no longer what everyone should buy. Instead, calculation cycles can be purchased from a centralized resource. One example is Amazon 's Elastic Compute Cloud (EC 2). It has more than 1 million customers in 2014 and grew 99% over the previous year. EC 2 is "infrastructure as a service" (IaaS). SaaS (Software as a Service) usually solves business-wide problems using cloud computing centralized and targeted application products. This approach is becoming more common and IDC expects sales to reach $ 50.8 billion by 2018. This has increased from $ 22.6 billion in the 2013 enterprise class SaaS application. SaaS ranges from collaboration technologies such as Citrix Gotomeeting to CRM such as SalesForce.
