We use the tool for networking purposes. It helps us to establish connections between machines and various components within a company's infrastructure. Specifically, the product serves as our account's core infrastructure component or our applications' cloud infrastructure. Through it, we can facilitate communication between different applications and expose them to external access when needed.
One important tool we use is Transit Gateway, which helps connect different parts of our network. We also use Internet Gateways, NAT Gateways, and Route Tables to ensure our applications run smoothly on AWS. While most people use these basics, some specialized tools, like Transit Gateway, are useful for specific needs.
The tool's most valuable feature is Transit Gateway. Security groups are like basic shields for your EC2 instances or virtual machines. They're the first line of defense, keeping your machines safe. Security groups are like bread for breakfast - a basic necessity for your instances to be secure.
The Amazon VPC subnetting feature allows you to divide your virtual network into different allocations, creating public and private subnets. This enables you to designate which machines belong to the public or private subnets. The crucial factor is the route table associated with each subnet, containing routing rules determining whether the subnet is public. Subnetting is essential for networking and is widely used regardless of whether you use AWS. It's a straightforward concept that requires understanding its usage.
Network ACLs are positioned outside your subnet and control traffic entering or leaving the subnet. They operate at the subnet level and can block specific IP addresses or port numbers from accessing the subnet.
On the other hand, security groups are applied at the instance level within the subnet. They regulate traffic to and from EC2 instances or virtual machines and determine which IP addresses and port numbers can communicate with the instances.
Integrating the tool with other AWS services was quite easy for me. AWS provides clear documentation on integrating one service with another, so I didn't find it difficult.
I recently worked on Transit Gateway, which connects multiple VPCs in one account and enables communication between them. However, I found the documentation unclear, possibly because few people encounter this situation. I figured it out and implemented it, but it required some research. Most people prefer using infrastructure as code rather than the UI for AWS tasks. However, the documentation may not always be up to date.
I haven't encountered any issues with the tool's stability.
Scaling resources isn't a concern for us when using Amazon VPC. With Amazon VPC, managed by AWS, scaling happens automatically. We don't need to stress about CPU or memory, as AWS handles scaling based on our network's needs. So, we do not need to worry about scaling up; it's all taken care of by AWS.
Unlike other services where you might need to consider scaling your application or service, with Amazon VPC, scalability is entirely managed by AWS. It's like creating a network adapter that can scale on its own without you needing to worry about CPU, memory, or utilization. AWS handles scaling automatically, and in my experience over the last ten years, I've never encountered scalability issues. Any issues that arose were typically due to specific account use cases or data center problems rather than scalability issues.
As an AWS account manager in my previous roles, I used to have weekly calls with them to improve our account. My experience with them is good.
Before choosing Amazon VPC, I used Oracle Cloud while working at Oracle for a year. However, while Oracle Cloud may be cheaper, it lacks the variety of options and scalability AWS offers. Therefore, I would recommend sticking with AWS.
I wouldn't say the initial setup is difficult. I find it more interesting and fulfilling to create things the right way from the start rather than going back to correct something built incorrectly by someone else.
The product is expensive.
The tool is a basic necessity if you're using AWS. It provides the essential networking infrastructure for any application to be deployed and managed in the AWS environment. I rate the overall solution an eight out of ten.
