Amazon Web services for Io. T: : Amazon EC 2 §EC 2 is an Infrastructure-as-a-service(Iaas) provided by Amazon §EC 2 delivers scalable, pay as you go compute capacity in the cloud. §EC 2 is a web service that provides computing capacity in the form of virtual machines that are launched in the Amazon’s cloud computing environment. §EC 2 can be used for several purposes of Io. T. §Example: Io. T developers can deploy Io. T applications on EC 2 , set up Io. T platforms with REST API services Dr Sumalatha Aradhya, Dept of CSE, SIT, Tumakuru 3

Amazon Web services for Io. T: : Amazon EC 2 v. Python program for launching the EC 2 instance Connection to EC 2 is established; ACCESS KEY and SECRET KEY are passed to the function The run_instances(. . ) function returns the reservation New instance Is launched AMI_ID, EC 2_KEY_HANDLE, INSTANCE_TYPE, SECGROUP_HAND Are passed to the Function. 4 Instances associated with reservation are obtained #1 The status of the instance associated with reservation is obtained 2 Dr Sumalatha Aradhya, Dept of CSE, SIT, Tumakuru 4

Amazon Web services for Io. T: : Amazon EC 2 v. Python program for stopping an EC 2 instance § conn. get_all_instances() is called to get all running instances. This function returns reservations. § ID of all instances associated with each reservation are obtained. § The instances are stopped by calling conn. stop_instances function to which the IDs of the instance to stop are passed.

Amazon Web services for Io. T: : Amazon Auto. Scaling §Amazon autoscaling allows automatically scaling Amazon EC 2 capacity up or down according to user defined conditions. §With autoscaling the users can increase the number of EC 2 instances running their applications seamlessly during their spikes in the application workloads to meet -> o application performance requirements o scale down capacity when the workload is low to save costs. §Autoscaling can be used for autoscaling Io. T applications and Io. T platforms deployed on Amazon EC 2 Dr Sumalatha Aradhya, Dept of CSE, SIT, Tumakuru 13

Let’s look into an example of creating Autoscaling group: Launch configuration contains instructions to launch new instances. After launch creation, instances gets associated with a new Autoscaling group. 1 Connection to Autoscaling service is established. AWA access key, secret key are passed to the functions 3 New Autoscaling group is 4 created #2 #1 Scale up and down policies are defined 5 Dr Sumalatha Aradhya, Dept of CSE, SIT, Tumakuru 15
