Examples are based on open source software whenever possible. As of December AWS operated 1. Software is part of every cloud platform and makes the difference for you as a customer. The information technology research firm Gartner has classified AWS as a leader in the Magic Quadrant for Cloud Infrastructure as a Service in for the fourth time. The speed and quality of innovation on the AWS platform is extremely high.
The first part of this book will guide you through your first steps with AWS and give you an idea of how you can use AWS to improve your IT infrastructure. Licensed to Thomas Snead n. You can use these services to host web sites run enterprise applications and mine tremendous amounts of data.
The term web service means services can be controlled via a web interface. The web interface can be used by machines or by humans via a graphical user interface. Aws books pdf free downloads most prominent services are EC2 which offers virtual servers and S3 which offers storage capacity. Services on AWS work well together you can use them to replicate your existing on-premises setup or design a new setup from scratch. Services are charged for on a pay-per-use pricing model. For exam- ple you can start a virtual server in Japan in the same way you can start a virtual server in Ireland.
This enables you to serve customers worldwide with a global infrastructure. The map in figure 1. In more general terms AWS is known as a cloud computing platform. Cloud computing or the cloud is a metaphor for supply and consumption of IT resources. The level of abstraction offered by the cloud may vary from virtual hardware to complex distributed systems.
Resources are available on demand in enormous quantities and paid for per use. The scale at which AWS operates computing networking and storage hardware is tremendous. It probably uses commodity components to save money compared to hardware that charges ex- tra for a brand name.
Handling of hardware failure is built into real-world processes and software. This CPU is optimized to power virtual servers from the c4 family. East U. West 1 U. West 2 Figure 1. The examples in this section will give you an idea of what you can do with AWS. His goal is to provide his custom- ers with a fast and reliable web shop.
He decided to host the aws books pdf free downloads shop on-premises and three years ago he rented servers in a data center. A web server handles requests from customers and a database stores product information and orders. By splitting dynamic and static content John reduced the load for his web servers and improved performance by delivering the static content over a content delivery network CDN. This frees him from managing these parts of the system decreases operational costs and improves quality, aws books pdf free downloads.
John split the capacity of aws books pdf free downloads old on-premises server into multiple smaller virtual serv- ers at no extra cost. If one of these virtual servers fails the load balancer will send customer requests to the other virtual servers, aws books pdf free downloads.
Figure 1. John started a proof-of-concept project and found that his web application can be transferred to AWS and that services are available to help improve his setup. Solving the equation is a challenge because there are many unknown factors, aws books pdf free downloads. Planning to meet future demands is nearly impossible. To prevent a supply gap you need to add extra capacity on top of the planned demand to prevent running short of resources.
The same was true when we planned the capacity of our IT infrastructure. When procuring hardware for a data center we always had to buy hardware based on the demands of the future. On AWS you can use services on demand. Planning capacity is less and less impor- tant. Scaling from one server to thousands of servers is possible. Storage can grow from gigabytes to petabytes. You can scale on demand thus replacing capacity plan- ning.
The ability to scale on demand is called elasticity by AWS. Public aws books pdf free downloads providers like AWS can offer needed capacity with a short waiting time. This allows you to address another problem: typical traffic patterns as shown in figure Think about the load on your infrastructure during the day versus at night on a week- day versus the weekend or before Christmas versus the rest of year. Auto-scaling is part of the EC2 service and helps you to scale the number of EC2 instances needed to fulfill the current load of your system.
We introduced auto- scaling groups in chapter 11 to ensure that a single virtual server was running even if an outage of an entire data center occurred. Servers can be decoupled synchronously with a load balancer or asynchronously with a queue. We introduced the concept of the stateless servers in part 3 of this book and explained how to use decoupling in chapter You need to launch uniform virtual servers when the number of requests grows and terminate virtual servers when the number of requests shrinks, aws books pdf free downloads.
To adapt to the current workload in an automated way you need to be able to launch and Examples are covered by the Free Tier The examples in this chapter are completely covered by the Free Tier. Keep in mind that this only applies if you created a fresh AWS account for this book and nothing else is going on in your AWS account.
The configuration and deployment of the blog- ging platform needs to be done during bootstrapping without human interaction. AWS offers a service to manage such a dynamic server pool called auto-scaling groups. If you use a template as you will in this chapter this dependency will be resolved by CloudFormation automatically.
Define the maximum and minimum number of servers. Update the desired number of virtual servers as needed. Terminate virtual servers.
Multiple virtual servers need to be stateless and decoupled, aws books pdf free downloads. Monitor the health of virtual servers by checking the instance state or the health of the application.
Launch a virtual server based on the template aws books pdf free downloads the launch configuration. Figure You use a launch configuration to define and configure new virtual servers. Table After you create a launch configuration you can create an auto-scaling group refer- encing it. The auto-scaling group defines the maximum minimum and desired num- ber of virtual servers. Desired means this number of servers should be running.
If the current number of servers is below the desired number the auto-scaling group will add servers. If the current number of servers is above the desired number servers will be terminated. The auto-scaling group also monitors whether EC2 instances are healthy and replaces broken instances. If you specify multiple subnets with the help of VPCZoneIdentifier for aws books pdf free downloads auto- scaling group EC2 instances will be evenly distributed among these subnets and thus among availability zones.
