What Is Public Cloud?
A public cloud is a platform that makes the standard cloud computing resources (e.g. storage, compute power, virtual machines..) available to users via the internet. Today, there are three main public cloud providers: AWS, Microsoft and Google. These providers deliver their services over the internet or through dedicated connections, and they use a fundamental pay-per-use approach.
- Lower operation costs - no investments in own IT infrastructure necessary
- Massive scalability to grow and expand as your business grows
- Quick, simple and on-demand upgrades - Minimum effort to operate and manage certain services - the provider installs, operates, maintains and monitors the hardware and software to deliver most services
- Secure underlying infrastructure to protect your data from threats
- More reliable and redundant than on-prem data centers from outages so your data is always available
The public cloud is hosted by one of the three big cloud providers (AWS, Microsoft, Google) and delivers IT resources and services (IaaS, PaaS, SaaS) over the internet to the public cloud. Customers pay in increments of usage for the resources they consume.
A private cloud offers many of the same capabilities as a public cloud, but it is owned and maintained by a single organization. The company could host the private cloud in its own data center or outsource the hosting and operations to a third-party provider.
Finally, a hybrid cloud combines the elements of the public and private cloud, and it’s intended to allow the customer to decide where they want to host their workloads as it makes most sense for their organization.
Is the Public Cloud Secure?
Companies often disqualify the public cloud because of security concerns on where their data or workloads live. However, this assessment of public cloud security can easily be debunked by taking into account the level of security measures and investment in the most up-to-date security solutions that public cloud providers make. Having a myriad of customers dependent on them, public cloud providers are not willing to take any risks so the level of talent hired and tools used to protect their customer’s data is something that no private cloud could surpass.
