Factors that Contributed to the Adoption of Cloud Services

Enterprise Security Magazine | Wednesday, February 20, 2019

Cloud computing tools are now indispensable for organizations. Modern cloud computing services are highly distributed, scalable and resilient and allow enterprises to connect remotely. Cloud service providers provide unlimited size, breadth of scope, and always-on availability, which has effectively displaced on-site computing and private data centers.

Few factors have contributed to the transformation of cloud services. Let’s delve deeper into the transformation journey of cloud services:

Application Transformation: Many companies have implemented Software-as-a-service (SaaS) platform for its various advantages. SaaS platform offers scalability which allows enterprises to scale up or down according to the business requirement. The SaaS service providers offer around the clock maintenance, support, and uptime services for the smooth functioning of an organization. The SaaS service providers offer a plethora of services, but the enterprises have to pay for only the subscribed application. The platform also enables businesses to host their internal apps in the cloud.

Network Transformation: In traditional corporate networks, applications were hosted in the data center. The access of these applications was provided only via their corporate network and within the confines of perimeter-based firewalls. These platforms restrain the growing traffic by filtering it through various security hardware appliances. Today, users demand remote access to connect directly to cloud services. The network transformation has allowed users to connect directly to cloud resources. The Software Defined Networking (SDN) enables companies to recognize traffic destination and route it to the corporate data center or out to the internet. This approach is considerably cheaper than the traditional approach of leased MPLS lines.

Security Transformation: With the amount of data produced every day, the traditional security model that relies on IP address for authentication does not provide sufficient security. Security solutions need to be adaptive and dynamic to mitigate any threats. Zero trust networking can establish a default-deny posture for all network data and traffic interactions. A corporate application can use SDN-enabled Zero trust environment for effective protection from the open internet.  A cloud-based platform uses granular policy engine where traffic goes through multiple filters. The platform uses a multi-tenant and scalable architecture which allows each user to be benefitted from the threat-intel derived from all user traffic.
