We provides resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers.
Ours simple web service interface allows you to obtain and configure capacity with minimal friction. It provides you with complete control of your computing resources and lets you run on ours proven computing environment.
Cloud Web Service presents a true virtual computing environment, allowing you to use web service interfaces to launch instances with a variety of operating systems, load them with your custom application environment, manage your network’s access permissions, and run your image using as many or few systems as you desire.
To use Cloud Web Service, you simply:
。Select a pre-configured, templated Machine Image (MI) to get up and running immediately. Or create an MI containing your applications, libraries, data, and associated configuration settings.
。Configure security and network access on your Cloud Web instance.
。Choose which instance type(s) you want, then start, terminate, and monitor as many instances of your MI as needed, using the web service APIs or the variety of management tools provided.
。Determine whether you want to run in multiple locations, utilize static IP endpoints, or attach persistent block storage to your instances.
。Pay only for the resources that you actually consume, like instance-hours or data transfer.
On-Demand Instances
On-Demand Instances let you pay for compute capacity by the hour with no long-term commitments or upfront payments. You can increase or decrease your compute capacity depending on the demands of your application and only pay the specified hourly rate for the instances you use. Our cloud web service always strives to have enough On-Demand capacity available to meet your needs, but during periods of very high demand, it is possible that you might not be able to launch specific On-Demand instance types in specific Availability Zones for short periods of time.
On-Demand Instances are recommended for:
。Users that want the low cost and flexibility of Cloud Web Service without any up-front payment or long-term commitment
。Applications with short term, spiky, or unpredictable workloads that cannot be interrupted
Reserved Instances
Reserved Instances provide you with a significant discount (up to 75%) compared to On-Demand Instance pricing. You are assured that your Reserved Instance will always be available for the operating system (e.g. Linux/UNIX or Windows) and Availability Zone in which you purchased it. For applications that have steady state needs, Reserved Instances can provide significant savings compared to using On-Demand Instances. Functionally, Reserved Instances and On-Demand Instances perform identically. Reserved Instances are recommended for:。Applications with steady state or predictable usage
。Applications that require reserved capacity
。Users able to make upfront payments to reduce their total computing costs even further
If your needs change, you can request to move your Reserved Instance to another Availability Zone within the same region, change its Network Platform, or, for Linux/UNIX RIs, modify the instance type of your reservation to another type in the same instance family at no additional cost.
