With Amazon EC2 , you can avoid upfront hardware investment, so you can quickly develop and deploy applications. By using Amazon EC2, you can start as many virtual servers as

Designing highly available applications is an important goal of architects. However, Designing highly available applications based on cloud computing platforms is different from designing traditional platforms. When cloud computing brings many new design challenges to architects, it also brings many new design concepts and available services.

AWS provides a wide variety of mirrors for users, but in most cases the AMI provided in the community do not fully meet our needs, such as the more disgusting some mirrored root partitions are only 10g, so we generally use the community's public image to create a EC2, And then configure her, and then hit a mirror for the project, Packer can make us more automated to generate AMI, we can write the original image and all the configuration of the content

When using the AWS Cloud Service, 90% uses the ELB service as a load-balanced solution, and using Elb is much more convenient than building load balancing yourself. 　　The main benefits of are: 1. Can monitor the health status of the instance at any time; 2. When the server is not normal, the ELB alert policy will automatically send messages to notify the Operators 3. When the server load reaches the threshold, the new server is automatically joine
