There has always been a debate when businesses have decided to leave an on-premise server to move onto a cloud environment. This debate has only got further intensified whenever the questions of security of AWS and other cloud providers like it are brought up. When you have an on-premise infrastructure you can enjoy a better control over it. You have a lot of confidence in the security being air-tight since there is no access from the outside. Businesses usually end up blaming a cloud hosting provider whenever there is a security lapse in the public cloud but in most cases, it is a faulty application which makes it vulnerable and compromises security. In this regard one can safely say that the AWS offers much better security than traditional on-premise infrastructures.
Reasons why the AWS offers higher security than an on-premise infrastructure:
- Perhaps the biggest benefit whenever you store data in the cloud using the AWS is the enterprise-grade security and encryption you can get. When you have an on-site server you are expected to set up firewalls and encryption software. Not only will you have to deploy these; you will also be expected to run these. But, this is likely to escalate costs and this expense is over and above the costs which you must bear to run the site in the first place. However, if you choose the AWS Cloud, all security protocols or encryption techniques are built into its architecture. So, you simply have to pay for the computing time and space you need. You are free to use the provider’s encryption and security systems without paying anything extra.
- Because the AWS is in charge of security of client data, they will make sure it is duly monitored and any suspicious activity detected at the earliest. There are special tools which enable the users to track everything that happens in the AWS environment. Users can also install various alerts to notify themselves of the activities which are not according to set norms.
- The AWS cloud will also offer many options to move data from an on-premise infrastructure to the cloud. This transferred data is then secured via TLS encryption. Users may make use of multiple private clouds so that they have better controls over the virtual environments, including IP addresses, route tables and network gateways. For instance, the Amazon Snowball is an external hard drive with massive capacity for transferring the whole data through hardwired connections. This data is couriered to data centers where the internal staff will then shift it to the cloud. Such connections are much safer than any in-house connection.
- The AWS is better than an on-site infrastructure in terms of security because it has been made to comply with norms like HIPAA, PCI etc. So, it was designed to comply with government rules and industry practices. Besides, the AWS also offers many tools which can protect data stored inside the cloud. There are even reporting tools, which will show the regulators whether the data complies with rules, or not.
- Replacement costs of AWS vs physical servers are much less than if you were to maintain an on-premise infrastructure. Businesses will be replacing their n-site systems maybe once in five years because beyond this time limit, the server will not function optimally. Although cloud services may have recurring costs, replacement costs are much less when you consider the long term profitability. The AWS already has a staggering infrastructure and costs of provisioning new accounts are nominal. So, the AWS customer will actually be paying much less compared to what they would for other services. Even the AWS Marketplace will offer intuitive products which are charged on hourly basis and there are no upfront charges.
So, to sum up, AWS has made it much more economical and safer for the small or medium sized companies to run smoothly because of their high end services and feature-rich plans. Earlier, such features could only be afforded by the big businesses. Security, for example, has many key implications and it is usually a weak security system which makes businesses favor on-premise structures to the cloud. But the AWS can provide almost the same enterprise-grade features which an on-site structure can offer. And it provides these features for both small businesses and Fortune 500 firms alike.
