AWS is offered on an on-demand, pay for what you use model.
AWS services are offered on a region- and availability zone-based partitioning. Accessing data in one region from EC2 instances in another imposes network traffic charges, so knowing where your data is located and your applications need to run is important if you want to keep costs down. Here are some points to keep in mind:.
In particular, EC2 instances can fail or quit responding unexpectedly, so incorporate resilience to resource failure into your application. Redundancy protects your application against resource failure. Use open source components as much as possible: Not only does open source software cost less, its licensing conditions make it much more congenial to sporadic use.
Proprietary software, by contrast, usually requires a significant license fee whether the software runs for five minutes or five years. While most are familiar with and use well-known AWS products like EC2 and S3, too many people fail to explore further into AWS and learn about other services that they could use for their applications. By leveraging additional AWS core and platform services, you can:.
Develop far richer applications: For example, by using ElasticSearch, you can provide sophisticated searching within your application. Deliver applications much more quickly: Instead of locating and implementing open source software packages, or even worse spending endless time negotiating proprietary license contracts, you can begin using AWS services to build out your application quickly and bring it into production sooner.
By using AWS services in your application, you are able to match your costs with your benefits, ensuring that your application achieves good economic outcomes. Build more scalable applications: Amazon designs all of its services to run at scale. If your application requires massive amounts of whatever AWS product it uses, you can be confident that Amazon has designed its services to scale to whatever level you may need.
AWS can support highly scalable applications. Think of AWS as offering infinite capacity. All those applications you had trouble with because they outgrew predicted user load, storage use, or network traffic? No problem anymore with AWS. Amazon provides the resource, you provide the application load. AWS cannot make your application failure-proof.
AWS can make it cost less to run your application.
AWS cannot make your application secure for you. In cloud computing environments, security is a shared responsibility. Amazon takes on security responsibility for what it provides — the computing environment — while you take on security responsibility for what you provide — application software components. In a moment, that beautiful, familiar RStudio interface appears! For security, it makes sense to change your password. Probably not a big risk, but why tempt fate? You can close your browser and open the window again any time you like, from any browser you like, using your new password.
But caveat emptor. You should also know how billing works. Still cheap to use for a few hours, but too costly to leave on all the time for fun. The stopped state is important for the other aspect of billing: data storage. Obviously, there are no charges when your instance is terminated, since you lose all stored data.
An instance that is stopped will retain all the loaded packages and local objects, but you have to log into AWS to start it. For any other kind, the usual fees apply.
