In a recent blog post, Colm Keegan, an analyst with Enterprise Strategy Group Inc. (ESG), in Milford, Mass., reported that a top concern in deploying integrated computing platforms (ICPs), such as converged and hyper-converged infrastructure, is falling prey to vendor lock-in.
Nevertheless, ESG data indicated substantial adoption of converged and hyper-converged infrastructure. In a recent survey of several hundred IT professionals, 33% said they have deployed ICPs, and only 17% indicated no interest at all. Among the factors driving adoption are scalability, lower total cost of ownership, ease of deployment and ease of management.
Keegan pointed out that deploying hyper-converged infrastructure doesn't have to mean committing to just one supplier, with do-it-yourself advocates mixing and matching vendor products and white box hardware. Some ICP vendors, such as NetApp and VCE, also offer turnkey platforms with support for various vendors -- standardized on Cisco for networking and VMware for server virtualization, for example.

Versa Networks joins the SD-WAN fray
Greg Ferro, the blogger behind Etherealmind, recently sat in on an Open Networking User Group event with Versa Networks, highlighting the vendor's new software-defined WAN (SD-WAN) offering. Founded by veterans of Juniper Networks, Versa targets managed service providers with the promise to replace MPLS backbones, lower costs and create agile, multi-tenant networks.
Ferro reported that, like many SD-WAN companies, Versa Networks employs network overlays to provide zero-touch provisioning. The company also uses Border Gateway Protocol (BGP), which it said ensures scalability.
In Ferro's view, Versa is arriving late in the SD-WAN market, competing against Viptela Inc. and Nuage Networks -- which are already selling products to managed service providers. He also expressed misgivings about Versa Networks' scalability, saying that BGP is far from the only important factor.

NSX: A stitch in time saves nine
On Network Inferno, blogger Anthony Burke has advice if you're about to embark on a VMware NSX deployment: Slow your roll. Burke said the idea for the post came out of a conversation with Packet Pushers bloggers Ethan Banks, Chris Wahl and Stephen Skinner, in which they offered this wisdom: "The first thing you do when you get NSX is ... do not deploy NSX."
Burke wrote that while it is possible to quickly install NSX in a brownfield environment, that ease of deployment doesn't negate the need for thoughtful design and preparation. To avoid a "bull-in-a-china-shop" scenario, he emphasized the importance of articulating a specific long-term goal and measurable milestones along the way.
