It’s clear that cloud computing is getting fast the dominant model used by companies to host data and applications and to develop new services.

Cloud Computing Adoption has grown rapidly over the past decade and will soon reach a tipping point where the use of cloud computing for application software, infrastructure software, business process services, and systems infrastructure will overtake traditional on-premises technology options in the next two or three years.

Recent events, such as the forced shift to hybrid working, have fueled further momentum for cloud services, and as cloud offerings continue to mature and evolve, adoption is likely to continue to expand.

That’s because cloud computing has some clear advantages. These include the ability to scale services almost infinitely based on demand without having to buy or maintain expensive hardware, and the ability to take advantage of new applications without having teams of engineers on the payroll to deploy them. and manage.

But the move to cloud computing also brings new challenges. And the biggest concern for many is safety.


It is true that one of the primary benefits of the cloud for businesses is the ability to hand over their systems and data to a cloud company with dedicated experts working to keep their systems secure. That is certainly the case with software as a service (SaaS), which for many companies takes the worry out of patching and maintaining software on their own servers.

But that doesn’t mean businesses can forget about security after moving to the cloud.

To take full advantage of cloud computing, you need to use more than one cloud company, moving data and workloads between a company’s own data center and the cloud, or between different clouds.

While the move to cloud computing may have removed some fundamental security concerns, the rise of the hybrid cloud has introduced a whole new set. These range from securing staff access to services, ensuring data is encrypted and not accidentally exposed to other cloud users, and ensuring data remains secure when switching between applications and cloud services. No two cloud services are exactly alike, and the risks increase as the use of cloud computing expands into new areas.

This special report on cloud computing security from ZDNet looks at some of the key issues and shows how cloud security is evolving. Moving to the cloud offers opportunities, but don’t ignore the security challenges.
