What is Cloud Computing?
The phrase ‘Cloud Computing’ has become almost a buzz-word in IT and, like many over-used terms, its meaning has become vague in many contexts. Put simply, it means using computers in a way where you don’t own your hardware. Instead, you rent an amount of hardware capacity from a third party utility company (Cloud provider) that you connect to over the internet. For this to work, you may also need to subscribe to specially configured applications or services from the Cloud provider.
Why is this a good thing?
The main benefit is that you save money in hardware. You don’t have to invest in expensive upgrades every time you need to increase speed or bandwidth. There’s no need to worry about whether you should buy extra kit to cover capacity for a sudden spike in traffic. You don’t have to constantly play catch-up, shelling out for the latest technology to keep up with security threats and network speeds. You let the Cloud provider worry about all this instead.
Why use AWS over other Cloud providers?
Usually, when you work with a Cloud provider you have to stipulate what you need: server capacity, bandwidth, number of users, likely application usage etc. You work out a service level agreement (SLA) and that sets your boundaries. If you need to scale up you negotiate changes to your SLA and the Cloud provider switches on the extra capacity for you.
With AWS, there is no SLA or contract. Storage capacity is set by how much data you have. Infrastructure is set by how many applications you’ve got running and how many users are connected. And bandwidth is set by how many web visitors are online right now. Practical, everyday usage comes first and technology scales to meet it. And you are billed for what you’ve actually used.
