The cloud makes any IT solution available as a Service.
IT and telecom services used to mean bulky hardware and software with limitations. Today, cloud services mean that almost any solution can be offered “as a service.” This includes Infrastructure as a Service (IaaS), Disaster Recovery as a Service (DRaaS), Desktop as a Service (DaaS), Backup as a Service (BaaS), or any other "X" aaS. Instead of having hardware on premises and software on those specific devices, the cloud allows these services to migrate offsite to a more resilient and capable cloud.
Although a hardcopy backup on servers at the office can be beneficial, that backup can be vulnerable to natural disaster or theft. BaaS and DRaaS protect a copy of your data in the cloud as a failsafe.
Rather than having software installed on each individual computer or unit, virtual desktops are stored in the provider’s data center. This allows you to have accessed through a secure web portal on any device, anywhere in the world.
Instead of directly communicating with Microsoft to manage users and services, Office 365 and email services are managed and supported by an authorized service provider.
IaaS allows you to rent space on secure servers in data centers. You can rent as much or as little space as you need on the servers. Within IaaS solutions, you can also have public or private service, and while both are secure, some company’s compliance requires that they have private IaaS.
Public cloud services such as AWS, Google Cloud, and MS Azure, are available to anyone, but it is easy to overspend on public cloud services. Managed public cloud providers manage the public cloud to your particular environment and business.
