Cloud Vs Legacy
Can Cloud Be The Answer To Legacy IT Problems?
The report is based on an analysis of more than 18,000 Common Vulnerabilities and Exposures (CVEs) logged to NIST’s National Vulnerability Database in 2020. It reveals that well over half (57%) were rated ‘high’ or ‘critical’ severity – the highest recorded figure for any year to date.
Our analysis also looks beyond severity scores, detailing the rise of low complexity vulnerabilities as well as those which require no user interaction to exploit.
These trends highlight the need for organisations to improve their understanding of the vulnerabilities actively exploited in the wild, as well as to adopt a multi-layered approach to vulnerability management.
The findings aren’t all bad news. There are also positive trends, such as a decrease in CVEs which require no privileges to exploit.
What Is Meant By Legacy IT?
Let us take a look at what the term ‘Legacy IT’ entails.
Legacy IT is the name given to self-managed systems that are deployed either within a company’s data centre (on-premises) or in a shared data centre (co-location) where the company leases space. The required equipment is generally purchased and owned by the company and is managed by its IT personnel.

What Is Cloud Computing?
Before we go headfirst into why cloud computing is the chosen one, let us first take a look at what cloud computing actually is.
“Cloud computing is the on-demand delivery of IT services from a third-party provider over the Internet. That means you consume a service provided by another company (aka the “service provider”), typically on a pay-as-you-use pricing model.”
So in layman terms, you pay a third-party provider to host your data on their storage system and pay only for the data you use.
Now there are several service models as well as deployment models for cloud services. Read more about them here.
Now that we are done with introductions, let us move on to the main question.
How Is Cloud Computing Better Than Legacy IT Solutions?
The introduction of cloud computing has resulted in a significant change in the way data is stored and accessed. Users are no longer required to store their files on private servers. Companies can share infrastructure, applications, and data around the Internet by combining Cloud and legacy systems.
