This is where you can get on demand EC2 instances to do the job for you. By saturating your hardware, this one job starts to impact your other workloads and you’re forced to make trade-offs where there are no good answers. However, you may find a big job comes along that requires a huge amount of data and processing - and you simply don’t have the resources on hand to be able to complete it. Perhaps you already have your own onsite servers and/or data centre server infrastructure with another provider. These administrators can be retrained to manage EC2 instances through the AWS portal, and even adopt standard tools to automate systems so they don’t waste time manually configuring instances. EC2 instance management is a whole lot simpler than physical server management, which frees up your incredibly valuable systems and network administrator’s time to work on other, more important tasks. These administrative staff are often deluged with jobs to do and will have more pressing priorities further up their task list, like fixing things that are currently broken than routine hardware maintenance. Hardware and networking experts aren’t only difficult to hire for, they also come at a substantial cost. Renting cloud resources means less investment into both hardware and the experienced personnel needed to manage it. Rather than investing in hardware infrastructure that you’ll need to manage and maintain, you can leave this to Amazon, and simply use these server resources like they are your own. We’ve listed out some of the key features of Amazon EC2 below that translate to real business benefits. If you don’t have your own servers already–for instance, you don’t have onsite racks or a contracted data centre you’re already happy with–then using EC2 simply makes sense. The Benefits of Amazon EC2: Amazon EC2 Features Keep reading and we’ll break down the different pricing options so you can select the ones that give you the best bang for your buck whilst maintaining the flexibility you need to be truly agile. EC2 machines by default come as pay-as-you-go you can fit your cost directly to your usage, whilst still getting discounts by entering into fixed-term contracts for your minimum footprint. In the case of EC2, you have the following: an instance volume which will be cleared when the instance shuts down, EBS volumes which are persistent per instance storage, EFS which is network attached storage, and S3 which gives you long-term storage that’s cheap as chips.Ĭost: Running virtual machines often comes with a fixed-term hardware commitment, you have to do time intensive capacity planning trying to predict the future and organise around funding cycles. Storage: VMs can be turned on and off, safe in the knowledge that the data that’s stored on them will still be there if it stays on the same hardware, or the storage is located on the network. Instead, with EC2 you get stronger performance guarantees and can always boot extra instance to share the load. When sharing resources you increase the risk of “noisy neighbours” impacting your workloads, as there’s no guarantee that when you need it someone else isn’t already using the memory. Unlike VMs however, EC2 instances cannot “share” this memory with other instances when it becomes available. Memory: Much like with VMs, when you set up an EC2 instance, you choose how much memory to allocate to it. While both options offer computing power that can power your core workloads, there are a few key differences: So are AWS EC2 instances just virtual machines in the cloud? Not quite. What’s the Difference Between VMs and EC2 Instances? Why rent servers? Because investing in that infrastructure for your own business can be costly both in time and money, especially if you aren’t always utilising these resources. What is Amazon EC2?Īmazon EC2 (Elastic Compute Cloud) is a service provided by the AWS cloud that allows anyone to rent servers offsite, at Amazon’s data centres located across the world. In this article, we'll introduce Amazon EC2, its benefits, AWS EC2 instance types and EC2 pricing. And everyone is always looking to lower their operating costs if it also means becoming more efficient and effective at the same time. Resources are scarce! Great employees, computing power, big data storage, even office floor space. Renting servers? If your compute power isn’t matching your workloads, then Amazon EC2 instances can be a solution–a solution to a problem you may not even realise you have.
