How Many Instances Can I Run on Amazon EC2 Free Tier?
As a data scientist or software engineer, you have probably come across Amazon Elastic Compute Cloud (EC2). In this blog post, we’ll delve into the capacity of the Amazon EC2 Free Tier. Specifically, we’ll answer the question: “How many instances can I run on Amazon EC2 free tier?”
What Is Amazon EC2 Free Tier?
Before we discuss the number of instances, let’s first understand what Amazon EC2 Free Tier is. Amazon EC2 is a web service that provides resizable compute capacity in the cloud. It allows developers to scale up or down their compute capacity based on the demands of their applications.
The Amazon EC2 Free Tier is designed to enable you to get hands-on experience with EC2 at no charge for 12 months following your AWS sign-up date. It’s a great way to test drive AWS services without any upfront investment.
Amazon EC2 Free Tier Offerings
The Free Tier offers 750 hours of EC2 running Linux, RHEL, or SLES t2.micro instance usage per month for one year. It also provides 750 hours of EC2 running Windows t2.micro instance usage per month for one year.
The t2.micro instance is well-suited for low to moderate traffic web servers, developer environments, and small database setups. With 1 vCPU and 1 GiB of memory, it can handle a surprising amount of work for small-scale applications.
Calculating the Number of Instances
Now, let’s get to the heart of the matter. How many instances can you run under the Free Tier? The answer depends on how you plan to use your 750 hours per month.
If you want to run one instance continuously, you can do so for the entire month. This is because there are approximately 720 hours in a month (30 days * 24 hours). So, running one instance for 720 hours will keep you within the 750-hour limit.
On the other hand, if you want to run more than one instance, you’ll need to calculate the usage based on the number of hours each instance will run. For example, if you want to run two instances, you can do so for about 375 hours per month (750 hours / 2). For three instances, it’s about 250 hours per month (750 hours / 3), and so on.
It’s important to note that the Free Tier 750-hour limit is not per instance but total. So, if you run two instances for 375 hours each in a month, you’ll have consumed your Free Tier limit.
Monitoring Your Usage
To avoid unexpectedly exceeding the Free Tier limit, you should monitor your usage. AWS provides the Free Tier usage metrics in the AWS Billing and Cost Management Dashboard. You can also set up a billing alert to notify you when your usage exceeds your preset limit.
Conclusion
So, how many instances can you run on Amazon EC2 Free Tier? The answer is, it depends. If you want to run instances all the time, you can only run one instance. But if you only need to run instances part of the time, you could potentially run more. The key is to monitor your usage and plan according to your needs.
Remember, the Amazon EC2 Free Tier is designed to give you experience with AWS. So, take advantage of this opportunity to learn and experiment with different configurations and services. But also be mindful of your usage to avoid unexpected charges.
Hopefully, this post has answered your question. Happy computing in the cloud!
