Amazon's latest cloud super hero, ElastiCache


This morning Amazon announced the public beta launch of Amazon ElastiCache, a new web service that makes it easy to deploy, operate, and scale an in-memory cache in the cloud. The service improves the performance of web applications by allowing you to retrieve information from a fast, managed, in-memory caching system, instead of relying entirely on slower disk-based databases.

Amazon ElastiCache is protocol-compliant with Memcached, a widely adopted memory object caching system, so code, applications, and tools that you use today with your existing Memcached environments will work seamlessly with the service. Amazon ElastiCache simplifies and offloads the management, monitoring, and operation of in-memory cache environments, enabling your engineering resources to focus on the differentiating parts of your applications. The service is ideal for many read-heavy application workloads (such as social networking, gaming, media sharing and Q&A portals) or compute-intensive workloads (such as a recommendation engine).

Using Amazon ElastiCache, you can add an in-memory cache to your application architecture in a matter of minutes. With a few clicks of the AWS Management Console, you can launch a Cache Cluster consisting of a collection of Cache Nodes, each running Memcached software. You can scale the amount of memory associated with your Cache Cluster in minutes by adding or deleting Cache Nodes to meet the demands of your changing workload. In addition, Amazon ElastiCache automatically detects and replaces failed Cache Nodes, providing a resilient system that mitigates the risk of overloaded databases, which slow website and application load times. Through integration with Amazon CloudWatch, Amazon ElastiCache provides enhanced visibility into key performance metrics associated with your Cache Nodes.

For more info about ElastiCache, you can visit Amazon ElastiCache detail page to learn more about the benefits of the service. You can easily get started with Amazon ElastiCache by viewing a quick demo or reviewing the Getting Started Guide, and launch a pre-configured Cache Cluster in minutes.

Amazon Web Services announces VPC Global Rollout and New Enterprise Features


Today Amazon announce the global rollout of Amazon Virtual Private Cloud (Amazon VPC) plus new enterprise capabilities for dedicated networking and identity management. These new capabilities are designed to support the security, network management, dedicated connectivity and access control requirements of enterprises when deploying mission critical applications in the cloud.

Amazon Virtual Private Cloud is now out of beta and is generally available in multiple Availability Zones in all AWS Regions (US East, US West, EU, Singapore, and Tokyo.) Using Amazon VPC, you can provision a private section of the AWS cloud where you can a create virtual network that you control, including selection of IP address range, creation of subnets, and configuration or route tables and network gateways. You can connect your Amazon VPC directly to the Internet while also extending your corporate data center to the cloud using encrypted VPN connections.
 

With today's global rollout of Amazon VPC, you can:
  • Provision multiple VPCs to support different use cases, for example, a production network, a staging network, and a development and test network.
  • Launch Amazon EC2 instances into subnets in different Availability Zones to protect applications from failure of a single location
  • Connect branch office locations to each other and to your Amazon VPC via encrypted VPN tunnels.
In addition, this rollout also includes support for Windows Server 2008 R2 and for Windows SQL Server Reserved Instances in Amazon VPC. To get started using Amazon VPC, visit http://aws.amazon.com/vpc


Amazon Direct Connect, also announced today, is a new service that enables you to bypass the Internet and deliver data to and from AWS via a private network connection. With a private connection, you can reduce networking latency and costs, and provide a more consistent network experience when moving data between AWS and your datacenters. With pay-as-you-go pricing and no minimum commitment, you pay only for the network ports used and the data transferred out from AWS over the private connection


AWS Direct Connect works with all AWS services and is available today for the US-East (Virginia) Region. Additional locations are planned for San Francisco Bay Area (San Jose), Los Angeles, Tokyo, and Singapore in the next several months. To get started using AWS Direct Connect, visit http://aws.amazon.com/directconnect.


AWS has also added new functionality for AWS Identity and Access Management (IAM) that enables “identity federation,” or the ability for you to use your existing corporate identities to grant secure and direct access to AWS resources without creating a new AWS identity for those users. This capability enables you to programmatically request security credentials, with configurable expiration and permissions, that grant your corporate identities access to AWS resources controlled by your business. To get started using AWS IAM, visit http://aws.amazon.com/iam.
