What is the difference between “The Cloud” and “Data Center”?
The main difference between the cloud vs. data center is that a data center refers to on-premise hardware while the cloud refers to off-premise computing. The cloud stores your data in the public cloud, while a data center stores your data on your own hardware.
Gartner, Inc. projected that the worldwide public cloud services market will grow more than 17.5% in 2019 alone, to total $214.3 billion. Global management consulting firm McKinsey & Company names cloud computing as one of the trends shaping enterprise IT infrastructure. Private data centers are diminishing, and McKinsey states that cloud providers are expected to account for 80% of shipped storage and server capacity by 2018.
Some enterprise organisations using the cloud have to depend on the cloud provider for cybersecurity, performance, and reliability. Sometime, a Cloud space could be shared with another.
Organisations who have their own data center are in control of their environment’s security, capacity, and performance. For these reasons, organisations that need high availability, require higher levels of performance, run mission-critical applications, or have strict compliance requirements may be better off with their own data center.
Some organizations use a hybrid of Data center and Cloud storage providers. However, it all depends on your organisation. An organisation that is partly regulated by the government, for instance, will find it more efficient and better to be self-reliant on a data center where they are in control. An organisation that cannot bear the expense of running their own data center will simply not be considering owning one.
One thing is for certain though, on the career front the future is bright, for those looking for IT careers in cloud computing.
