In the last two blogs, I talked about the reasons for IT Transformation, understanding Enterprise Environment and how to effectively set management goals. As more and more companies begin to move towards IT Transformation, there are mistakes that businesses should be weary of. Today I will discuss the pitfalls that can slump the IT transformation process, as well as, the services Cisco has been developing to help Enterprise on the journey to IT transformation. Read More »
In my last blog, I established reasons behind today’s need for IT Transformation. We know that CIOs hope to cut their budget in half, but this will be difficult unless they understand their Enterprise Environment, as well as, the management goals that align with their organization’s overall IT transformation efforts. Today we will take a deeper dive into understanding both. Because there is no “one size fits all” way of embarking on an IT Transformation journey, it is important that each organization looking to begin this process makes their own set of assessments, starting with a baseline assessment of their Enterprise Environment: Read More »
IT organizations face several challenges: a globalizing economy, the increasing cost of IT ownership, business users directly going to public Cloud providers, the difficulty of operating complex environments, effectively enabling innovation as well as variety of risks around security and compliance. Given these challenges, IT decision makers must innovate and conduct business differently in order to remain effective. Data shows that despite years of IT cost reduction programs, the industry on average has only managed to shift an additional 1% of IT spend towards growth and innovation.
Does transforming your IT mean moving from a cost center to a business enabler? Changing your architecture to include Cloud? Redesigning applications or selecting off-the-shelf application? Or moving from a centralized IT delivery to IT services broker? A majority of business leaders have said “yes” to all of the above. Read More »
This is the first of a four part series on the convergence of IT and OT (Operational Technologies)
Part 2 will cover the impact of the transition to IP on Physical Security and the convergence of Physical and Cyber Security.
Part 3 will discuss the convergence of IT and OT -- Operational Technology of all types outside the traditional realm of Information Processing.
Part 4 will look at how to actually make the transition to a converged IT/OT infrastructure and tips on overcoming the challenges.
Those of us in the Energy Industry know that the utilities segment is in transition. The network architecture, in particular, is undergoing change -- change that will bring challenges as well as opportunities for both Cisco and our customers.
Almost every communication application started as point to point serial — including computer communications. But the simple geometry problem of how many lines are needed to connect every vertex (node) of a polygon to every other vertex [ n(n-3)/2 if you’re curious ] shows that as the number of nodes grows, connecting each one to every other one quickly becomes infeasible.
The need to interconnect more and more devices lead to multi-drop or bus topologies and challenges of how to deal with sorting out who gets to talk when and the solutions of token passing, polling and TDM.
Circuit switching was a big breakthrough developed out of necessity as the number of telephone handsets exploded. Interestingly enough, look at the hierarchical topology of trunking and local switching and you may recognize analog similarity to NAT.
Initial application of networking often occurs as the use of Ethernet to replace serial communication with flat, layer-2 networks, to interconnect multiple nodes with polling and TDM used exactly as they were in serial systems. That’s where most SCADA systems still live today and why there are relatively few monitored points, limited by how quickly the polling loop can be traversed. Imagine trying to run the internet that way?
Fast forward and almost every industry and industrial application that started off as serial or circuit switched has migrated or is migrating to packet switched as IP packet technology has made astonishing progress along the price/performance curve.
High performance IP is now able to offer latency performance that used to require dedicated connections. Along with IP have come the tools to manage, diagnose, repair and secure the communication network. Relative to the billions of dollars invested by companies around the world in tools, security, management, etc. for IP, the investments being made in securing and improving serial or TDM are almost nonexistent.
Globally, Service Providers who built their industry on circuit switched analog and TDM are terminating those services as they move to complete their transition to IP.
Cisco continues to play a key role in transitioning serial/TDM technology to IP, helping customers get full benefit of the robust performance and security capabilities and features IP offers. Customers who have received End of Service notices for Framerelay are scrambling to find alternatives and at the same time achieve regulatory compliance.
As Operation Technology groups outside of IT increasingly use IT Information & Communication Technology (ICT), they need the same capabilities as IT.
What does this mean for Cisco and our customers?
Relationships with the business, including the operations side of the business are key. Budget is increasingly in the hands of the business rather than IT. As a result, Cisco and our customers’ IT departments are increasingly collaborating with the operational side of the business -- especially the OT, or ‘Operational Technologies’ part of our customer’s organization.
Cisco has specialized industry sales support teams in a group called CVA (Cisco Value Acceleration) Group, which I’m a part of, as well as Cisco Advanced Services and other Cisco Business Units (especially the IOTG, or Internet of Things Group) along with groups such as the Cisco Global Industries Center of Expertise (GICE) to understand the trends, business imperatives and compelling events creating opportunity with customers.
