Welcome to Continuous Improvement, the podcast where we dive deep into the world of Amazon Web Services (AWS). I’m your host, Victor Leung, an AWS community builder, here to help you navigate the vast world of cloud computing. In today’s episode, we’ll be discussing the fundamental aspects of AWS and how it can transform your business. So, let’s get started!

So, what is AWS? Well, it’s the world’s most comprehensive and well-adopted cloud platform. Customers across the globe trust AWS to power their infrastructure and applications, allowing them to lower costs, become more agile, and innovate faster.

AWS provides on-demand delivery of technology services via the internet with pay-as-you-go pricing. This means that you only pay for the services you use, without any upfront costs or ongoing commitments. It’s a flexible and cost-effective solution for running any type of application.

One of the key advantages of AWS is the wide range of services and features it offers. With AWS, you have access to more services and features than any other cloud provider, making it faster, easier, and more cost-effective to move your existing applications to the cloud and build new innovative solutions.

When it comes to scaling your applications, AWS has you covered with its globally deployed infrastructure. With 84 Availability Zones within 26 geographic regions worldwide and more on the way, you can easily scale your application to meet growing demand. You can choose the region closest to you and your customers, ensuring low latency and high performance.

Now, let’s talk about computing power on the AWS platform. One of the key services for deploying servers is Amazon EC2, also known as Elastic Compute Cloud. With EC2, you have a wide range of instance types to choose from, each optimized for different use cases. The selection process involves considering the CPU, memory, storage, and network performance requirements of your application.

But what happens if you choose the wrong instance type? No worries! With AWS, you have the flexibility to change the instance type even after you’ve started an EC2 instance. Simply stop the instance, change the type, and start it again. It’s that easy.

To ensure optimal performance and stability, AWS provides various CloudWatch metrics for your EC2 instances. These metrics include CPU utilization, disk operations, network traffic, and more. You can also install the CloudWatch agent to collect memory metrics and track log files.

Now, let’s move on to another critical aspect of AWS: high availability and fault tolerance. AWS offers various features to ensure your applications are always up and running, even in the face of disasters. One of these features is the ability to deploy your application across multiple Availability Zones. By distributing your infrastructure, you can ensure that your application remains available even if one zone goes down.

In case of larger-scale disasters or outages, you can leverage multi-region deployments. For example, deploying your website in Singapore and setting up a backup environment in Hong Kong. By utilizing Amazon Route53, you can easily switch your domain name and redirect
