For the past 20 years if not longer, the network has been the lifeblood of enterprises as it is the foundation on which connectivity is built. It is hard to imagine that most any corporate organization can do business without connectivity, so much so that the networks’ power and ubiquity has made it a baseline assumption. Unfortunately, IT spends too much time worrying about the connection and not enough on how we enable the services that use that connection. Therefore, it is the job of…
Data center monitoring and analytics (M&A) requires a comprehensive metadata collection platform that leverages advanced Big Data processing, Machine Learning (ML), and Artificial Intelligence (AI) analytics to perform application to network visibility, correlation, and modeling for data center network fabrics. The platform collects network stream metadata (not actual payload data) from across the data center network and devices using telemetry technologies. This data is stored as data lakes and processed using Big Data technology. The structure allows rapid access, searching, and processing of the huge…
As reliance on SaaS applications increases and workloads move to the cloud, Wide Area Network (WAN) requirements increase in scope and are top of mind for many businesses and thought leaders responsible for their digital transformation strategy. Rather than trying to fix each element of their network architecture individually, organizations are beginning to look at their networks more holistically. While there has been a lot of focus on SD-WAN as a primary driver of WAN modernization, at Cisco we believe that it’s just one critical…
Summary Software-defined networking (SDN) and network functions virtualization (NFV) are the technologies driving next generation network transformation; but the factors impacting faster SDN/NFV adoption are the same ones slowing the road to 5G. While there are many technical challenges, it comes down to the fact that this is a paradigm shift. Running a hybrid networking environment can be challenging; communications service providers (CSPs) simply can’t afford to interrupt mission critical services inadvertently while upgrading their networks. Also, investing in network transformation takes buy-in internally and…
Why should we care about monitoring and visibility into Software Defined Wide Area Networks (SD-WAN) in the first place? Well, for one thing, analysts’ consensus estimates that the SD-WAN market will grow from roughly $90M in 2017 to over $4B in 2020. Digital economy demands agility in responding to user requirements and delivering superb user experience. The former is achieved via agile development and various software defined technologies. The latter has to be managed. SD-WAN is the software defined networking solution for the edge and…
I remember leaving camp with my parents on visiting day, late 70s, New Hampshire. It was hot and sticky and bright green out as we drove to from Lake Arlington to Hanover, to the Dartmouth campus and the Kiewit Computation Center. Inside was cool and crisp. White and sterile, with the hint of a hum among the rows of machines. On display was connectivity, and it was mesmerizing. A few years later, in 1982, I leveraged this family memory and asked my father for an…
The global digital transformation market is expected to continue to grow. At the forefront of that transformation are Software Defined Networking (SDN) and Network Function Virtualization (NFV) technologies, which are creating new opportunities to redefine the customer experience by delivering agile and on-demand services. While there’s a lot of industry buzz about these services as we approach ONUG Spring 2018 in San Francisco, and many people generally understand SDN and NFV technologies, there seems to be a gap when it comes to the practical application…
The world of networking is undergoing a major shift over the past few years. Micro services and containers in application stack has put new challenges to networking engineers across enterprises to build a faster and leaner network stack. Greater visibility into end-to-end network flow and granular control is another big requirement. It means that organizations need to keep up with the agility of ever-changing application landscape. In fast-paced environment, network agility can be achieved through Software Defined Networking (SDN), Network Function Virtualization (NFV) and Programmable…
The more networks have evolved and the more complex data center architectures have become, organizations are realizing they’ve got time bombs latent in their network, just waiting for the right set of circumstances to take down critical portions of their infrastructure. In the past, a configuration error might cause a blip in the network that went unnoticed. With today’s networks so intimately tied to business, each error can cost many millions of dollars and become front-page news. A surprisingly simple way out of this dilemma…
If software is indeed moving to the cloud, new tools will be required for debugging when errors culminate into outages. This is due to the reliance on higher level abstractions through monitoring now that there is no physical access to the servers running the applications. Lately, I’ve been thinking a lot about the types of assurances (and startup solutions) enterprises will need in a cloud native world to guarantee uptime. Site Reliability Engineering is a functional role in most businesses today, but has seen a…
