A revolution is underway. Nearly every automotive company is developing autonomous self driving vehicles. In fact, not long ago, an autonomous taxi service (Waymo), launched in Arizona. During the last few years, IoT applications have become increasingly commonplace across several industries, from retail to logistics to transport/automotive. According to various forecast models, the number if IoT... Read more

The power of public cloud has transformed many industries. Many innovative startups may not have ever seen light of day if they could not harness the power of public cloud. Public cloud providers such as AWS, Azure and GCP have made it much easier to start a business as infrastructure is ubiquitously available in the cloud. Not only have new startups taken advantage of the unlimited computing... Read more

For sign 7 of DC Network Transformation, we are picking a popular public cloud construct whose impact can be monumental when broadly deployed in mainstream data centers: Virtual Private Cloud (VPC) On-Prem.  VPC, despite its compute-centric name, is actually a new unit of networking in AWS and Google public clouds; in Azure, it is called VNet. VPCs/VNets are logical networks and enable cloud... Read more

Network analysis, telemetry and visualization are critical in any DC network transformation project for rapidly identifying application performance/connectivity issues, for capacity planning as well as for predictive network behaviors. Hence, we chose Network Analytics for the 6th Sign that DC networks are transforming.Why traditional box-based networks lack analytics?In box-by-box networking, a... Read more

Network security (who can talk to whom) is a fundamental construct of any data center network deployment. Hence, we have selected Controller-based ACL as the 5th sign of DC network transformation.  What are the typical challenges with traditional box-based ACLs?A traditional box-based network provides access controls, via ACLs and VLAN/subnet-based policies, but they were hardwired to the port or...

DC operators have been overwhelmed with network complexity during the last 20 years, and hence our sign no. 4 focuses on Network Automation. Because traditional DC networks operated on a box-by-box basis, these networking tasks needed to be performed with great care and skilled personnel, hence causing a lot of delays. Also, the fact that the network is the lifeline of applications, it’s critical... Read more

On to Sign 3 – Software Controls. Traditional box-by-box networking has often been mocked as “hardware-defined” or “hardware controlled.” Cloud Giants figured out a decade ago that software controls are critical to make the underlying hardware networking infrastructure logically centralized. According to the Google design principle: Logically centralize.. with a hierarchical control plane...... Read more

The 2nd concrete sign of DC network transformation is deployment topology that leverages core & pod design principles. A pod is a self-contained unit of compute, network and storage; in our context, a “pod” is used interchangeably with a “pod network.” Most traditional network designs have been based on a 20-year architectural premise, based on a N-tier hierarchical topology (see diagram...
