Amazon Web Services (AWS), a subsidiary of Amazon, is a cloud computing service provider which offers its services to organizations and individuals on a payment basis. One of the biggest game changers in the IT industry, AWS was the top paying certification according to a 2016 article in Forbes. While multinational companies and firms like Adobe, BMW, Canon, Capital One, Financial Times etc are moving into AWS cloud services, job opportunities for those with the right kind of certification and qualification will hike, which shows us that career and future in AWS is brilliant.
According to the Global Knowledge Study 2016, AWS ranked first in the top paying certification with an annual salary of $125,871 and the ‘Global Knowledge IT skills and salary report 2017’ states that AWS certification is the most relevant certification with most claims and highest salary around the world. So when it comes to a career, an AWS certification is stunning.
The AWS cloud services like what most people think are not limited to computing and storage. It also includes networking, security, analytics, etc. Amazon Elastic Compute Cloud, also known as Amazon EC2 is such a kind of web service from AWS. It’s basically a virtual web server used for running application for AWS. The virtual servers are called instances with interfaces designed to provide the user complete control over the computing complexities with its secure and scalable computing capacity. A wide range of instances is available from Amazon EC2 that focuses on giving different computing capacity and use cases with the ability to run in different platforms. The following image shows the general categories of instances;
The EC2 instances before the release of T3 instance
The new member to join the club of general purpose instance is the Amazon EC2 T3 instance. Launched by the Amazon on August 21, 2018, T3 is the next generation burstable general purpose instance which is cost effective and has a 30% better price performance compared to the previous instance. Burstable instances are the ones that offer a baseline of CPU performances that can have quick access to high-level CPU performance when needed. T3 is designed for workloads that don’t require constant high CPU usage but can have high processing power when required as long as you need. Just like the case of T1 and T2 a considerable processing power is provided for T3 too. The instances are powered by Intel Xeon Scalable Processors and the AWS Nitro System.
You can launch the instances in seven different sizes
T3 gains CPU credits while it runs below the threshold value and uses the credits collected to burst the CPU power above the baseline when higher processing is wanted. You can imagine it as a bucket which collects the incoming credit supply while the CPU is below the baseline. The credits accumulate till its limit, ie 24 hours. The credits are consumed when the application requires more resources and when the load is higher than the incoming supply, the bucket will get empty.

If the instance runs at higher CPU utilization than the baseline for a longer time, then, there will be an extra charge of $0.05 per vCPU-hour. This means that you can select the desired T3 instance based on your requirements and the bursting will cover the extra power necessary and this scalable property can help the user in many applications. Designed for CPU usages with occasional usage spikes, this next generation instance covers a wide spectrum of workload services keeping the cost as low as possible. The main features of a T3 instance include:
Powered by the Nitro system, T3 instances also support network and EBS bursting. The EBS bursting ranges from 1.5 Gbps to 2.05 Gbps while network can burst up to 5 Gbps for all instances. Just like the recent instances, T3 must be launched in within a Virtual Private Cloud using an HVM AMI. The T3 instances are now available in Ohio, N. Virginia, N. California, Oregon, Canada, Ireland, London, Frankfurt, São Paulo, Tokyo, Singapore, and Sydney regions. In conclusion, the T3 instance may have some default properties to T2, but if you look closely into the technical aspects, you can see that the T3 offers a better price point and the unlimited burst with more number of vCPU gives T3 the upper hand over T2.
