With AWS, developers can create complex applications for meeting different needs of the enterprise. AWS developers are required to provide reliable and cost-effective services on the Amazon layer.
The best part about AWS is that it can be used as a platform-as-a-service and is available on a pay-as –you-go since it only depends on usage. This means that there is no need for upfront expenditures. There is absolutely no maintenance costs involved since the overall hardware and systems are maintained and serviced by Amazon.
The virtual infrastructure is quite necessary in today’s world since it saves on costs and future expenditure. An infrastructure can put on within some time and it is always ready to take up tests. If a real infrastructure was set up to set up a real-world IT shop, it would have been humungous to put it all together. A virtual infrastructure in AWS is elastic and can be scaled up and down based on demand. Companies are using the concept of elastic computing for use.
Elastic Cloud Compute (EC2)
Amazon EC2 resembles the computational brain behind AWS. Most developers can utilize multiple instances for supporting complex computational tasks. Multiple instances can be configured and they can be of several sizes since micro instances take up 613 MB of RAM while the biggest ones occupy 15GB of RAM.
Finally, EC2 instances can also be deployed in diverse and various geographic locations where Amazon's data centers are located originally. The deployment can also be done in various availability zones or even in multiple areas. Load balancing can be achieved by deploying the system in more than one area.
AWS offers freedom from big infrastructure investment and also lessens the cost involved along with other resources. The maintenance part opens up avenues for innovating new things without having unnecessary overheads. One can focus on particular core business ideas without having to worry about the number of servers or the overall infrastructure like disk space etc. Amazon estimates presume that building and maintaining infrastructures takes up more than 70% time while the rest of the 30 percent is allocated to power ideas. Amazon takes up worry of infrastructure without having you to concentrate on the mundane aspects and actually concentrating on bringing creative ideas to life.
Entrepreneurs are capable of creating scalable and reliable applications by using virtual setup provided by the AWS which does not cost much upfront or even in the future. Amazon Web Services is much better than traditional application-hosting platforms since the latter use huge server farms for maintenance and for redressing spikes. The redundancy levels are usually high too.
Amazon provides two levels of service including free forum-based support and paid support packages. The company publishes the health status of its Web services regularly and all issues are also listed down for public access. During any service outage, the system reports every half an hour before the issue is resolved. Amazon even provides standards-based SOAP interfaces for interacting with web services. Command-line tools can be made available for EC2 management. The REST interface is simple to use too!
