AWS Compute Fundamentals
AWS Elastic Beanstalk
This course provides detail on the AWS Compute services relevant to the Developer - Associate exam. We shall be looking at Amazon EC2, AWS Elastic Beanstalk, and AWS Lambda.
- Understand when you use Amazon EC2
- Learn about the components of Amazon EC2
- How to create and deploy EC2 services
- Understand what EC2 auto scaling is
- Be able to configure auto-scaling launch configurations, launch templates, and auto-scaling groups
- The ability to explain what AWS Elastic Beanstalk is and what it is used for
- The knowledge of the different environments that Elastic Beanstalk provides, allowing you to select the most appropriate option for your needs
- An explanation of how to configure the service and some of the parameters that you can alter to meet your application requirements
- The knowledge of the different monitoring options available for assessing your environment and resources health
- Be able to explain what AWS Lambda is and what its uses are
- Define the components used within Lambda
- Explain the different elements of a Lambda function through its creation
- Understand the key differences between policies used within Lambda
- Recognize how event sources and event mappings are managed for both synchronous and asynchronous invocations
- Discover how Amazon CloudWatch can monitor metrics and logs to isolate issues with your functions
- Learn how to check for common errors that might be causing your functions to fail
Hello, and welcome to this very short lecture where we are going to answer the question, what is Compute in AWS? Before we begin to explore Compute services, resources and features, we must first understand what is meant by the term Compute. So what is it?
Put simply, Compute resources can be considered the brains and processing power required by applications and systems to carry out computational tasks via a series of instructions. So essentially Compute is closely related to common server components, which many of you will already be familiar with, such as CPUs and RAM. With that in mind, a physical server within a data center would be considered a Compute resource, as it may have multiple CPUs and many gigs of RAM to process instructions given by the operating system and applications.
Within AWS, there are a number of different services and features that offer Compute power to provide different functions. Some of these services provide Compute, which can comprise of utilizing hundreds of EC2 instances, or virtual servers, which may be used continuously for months or even years, processing millions upon millions of instructions. On the other end of this scale, you may only utilize a hew hundred milliseconds of Compute resource to execute just a few lines of code within AWS Lambda before relinquishing that Compute power. Compute resources can be consumed in different quantities, for different lengths of time across a range of categories, offering a wide scope of performance and benefit options. So it will really depend on your requirements as to which Compute resource you use within AWS.
As a quick high-level reference, AWS offers a Cloud Compute Index, which can be found using the link onscreen. And this shows different examples and scenarios of where you might use different Compute deployment units. That brings me to the end of this very short lecture. Now we are aware of what Compute is, let's start by looking at some of the services offered by AWS that provide this Compute resource, starting with Elastic Cloud Compute, EC2.
