Use Cases and Deployment Scope

We use EC2 for almost all our operations, they are an excellent option for workloads like Web Servers like Apache and nginx, Application Servers like WebLogic, Java Servers, and even as Database Servers with Oracle and Microsoft SQL Server running on them. There plenty of choices to choose on how the EC2 is so they accommodate almost any software on them.

Pros

They start and stop quit fast
They can be created and terminated (deleted) very fast
They can scale-up or scale-down almost immediately (just require a restart)

Cons

You can not scale up or down without a restart
You can increase the size of the volumen (hard disk) but you can't decrease its size
By default any Linux OS on EC2 doesn't have a GUI

Likelihood to Recommend

AWS EC2 is well suited for almost any scenario, you can run any software that is compatible (x86_64, arm, mac), and you have plenty of instances types to choose with little or massive memory, the same for CPU and disk space.
You even can run in a non-virtual EC2, that is a physical server we you have all the resources available to you, perfect for some very strict industries or by some licenses rules.

I can't think of an scenario where EC2 is not appropriate.

Use Cases and Deployment Scope

We primarily use Amazon Elastic Compute Cloud (EC2) instances for running our Splunk deployments on AWS, Amazon Elastic Compute Cloud (EC2) gives us the flexibility to choose from a wide range of server types at an hourly rate, or for even lower prices with upfront commitment - it allows us to quickly make changes to the instance types we are interested in and perform testing before then making long-term savings by committing to instances for the next 12 months.

Pros

Instant access to servers
Wide range of instance types available
Ultimate flexibility

Cons

Switching hardware types may require application changes
Security patching can be onerous if not automated
It is easy to end up having more running than you need

Likelihood to Recommend

Amazon Elastic Compute Cloud (EC2) is particularly good for running monolithic workloads which are not easy to containerise or run on microservices with other AWS services. This includes off-the-shelf applications from vendors who supply closed-source software and expect a full server for installation. There are other benefits depending on instance types which are an advantage over function-as-a-service type resource, such as direct attached fast storage, high memory, network or graphics requirements.

May 11, 2023

Use Cases and Deployment Scope

We use EC2 to rapidly and efficiently scale up or down as needed for our customers while still providing a secure and dependable environment. It enables us to swiftly supply new instances and adjust resource allocation as necessary.We also use EC2 to provide high-performance computing, process data, and do analytics.

Pros

its pay-as-you-go pricing approach
effectively provide and manage compute resources
adjust resource allocation

Cons

nothing as such but some more cross functional policies can be added

Likelihood to Recommend

Good Scenario : EC2 is a wonderful option when you need to execute a lot of compute-intensive tasks, like producing videos or performing scientific calculations. It is the best option for applications that call for a lot of processing power due to its fast CPUs and potent GPUs.Bad Scenario : The best option for conducting lengthy tasks might not be EC2. Since EC2 instances are made to be quickly spun up and down, they might not be the greatest option for jobs that call for prolonged compute cycles.

Amazon Elastic Compute Cloud review for Machine Learning Developers

Rating: 8 out of 10

July 7, 2022

Use Cases and Deployment Scope

I use it for training machine learning models. I use the Deep Learning AMIs available to spin up Amazon Elastic Compute Cloud instances and then use that to train large models.

I use the GPU-based Amazon Elastic Compute Cloud instances, as for training large models good GPUs with high memory are required. I connect the instance to the S3 bucket where I store that data.

Pros

Deep Learning AMIs.
Ubuntu Instances.
Data Security by hiding Public IPs.
Support for VPN for data security.
Always ON, never slows down.

Cons

Documentation
Tutorials for beginners.
Simplifying Dashboard.

Likelihood to Recommend

It is good for training big models when getting access to GPU is not possible. If you've access to GPU, then training them on the computer makes more sense as it helps in reducing the cost.

Prefer it when you just can't manage on-premise machines as they require a lot of maintenance and get down quite often. Amazon Elastic Compute Cloud takes off that burden from head, i.e. no worry of maintenance and is always ON. Also provide the functionality of scaling up when required.
