One of the unintended consequences of cloud is the operational inconsistency
it introduces. That inconsistency is introduced because cloud commoditizes
the infrastructure we're used to having control over and visibility into.
everything from the core network to the application services upon which
business and operations relies to ensure performance, availability and
security are often times obscured behind simplified services whose policies
and configurations cannot be reconciled with those we maintain on-premise.
You do not provision resources or deploy apps the same way in the cloud as
you do in the data center. In fact, it's unlikely you'll provision resources
or deploy apps the same way in cloud A as you do in cloud B. And even if you
implement a private cloud, the way you provision resources and deploys apps
will almost certainly be different than how you do it ... (more)
Operationalizing the Network on Target with F5 and Chef
Operationalizing the network continues to be a driving force behind DevOps
and SDN. The ability to solve real problems using programmability to automate
and orchestrate infrastructure provisioning and configuration across the
application release process remains the hope for many interested in one or
the other - and often times both.
A recent Avaya sponsored, Dynamic Markets survey (reg required) dove deep
into the demesne of SDN and found that many of the problems companies have -
and expect to be solved by SDN - are directl... (more)
How Microservices Are Breaking (up) the Network
It's not just apps that are decomposing, it's the network, too.
The network is bifurcating. On the one side is rock solid reliability founded
on the premise of permanence and infrequent change. On the other is
flexibility borne of transience, immutability and rapid change.
There are, by virtue of this change in application architecture from the
monolithic to the microservice model, changes necessary in the network.
Specifically to the means by which the network delivers the application
services upon which apps rely to be themselves d... (more)
Purpose-driven Networking: Where IoT and Microservices Intersect
The purpose of communication between things and apps will become more
critical to understand and act upon as the number of things continues to grow
One of the neat things about microservices is the ability to segment
functional actions into scalability domains. Login, browsing, and checkout
are separate functional domains that can each be scaled according to demand.
While one hopes that checkout is similarly in demand, it is unlikely to be as
popular as browsing, after all, and the days of wasting expensive money on ... (more)
Programmability in the Network, of the Network and by the Network
Programmability is an integral component of just about every emergent
technology and trend today. Cloud? It's based on the ability of providers
(public or private) to abstract, automate and orchestrate the network using
programmability. DevOps? A significant tenet of DevOps relies on automation,
which in turn requires programmability of the infrastructure (network and
application) upon which apps are deployed. SDN? Again, a core principle of
SDN is the ability to programmatically modify the behavior of the network ... (more)
