Cloud usage delivers higher levels of security on three principal dimensions.
Firstly, infrastructure is physically more secure – often more secure than would otherwise be achieved with on-premises equipment. Infrastructure is located in high security data centres with extensive physical security and redundancy.
Regulatory compliance is a critical factor for a number of organisations. Cloud providers have addressed this in a number of ways. These include:
- Independent certification of industry standard regulations, such as PCI compliance;
- Taking advantage of isolated resources, dedicated hardware, identity and access management; and
- Granular logging that can be used both for troubleshooting and for compliance auditing.
Cloud infrastructure enables the building of truly fault tolerant networks. Providers such as Amazon AWS and Microsoft Azure have numerous locations globally, allowing for compressive redundancy in the highly unlikely event of an outage as well as ensuring data compliance in certain jurisdictions.
The end result, when utilising cloud environments with comprehensive security and redundancy policies and procedures, is the likelihood of having security breach or even an infrastructure outage is an order of magnitude lower than would otherwise be possible with on-premises equipment.
