SD-WAN growth - Vendors and Operators

SD‐WAN uses software and cloud‐based technologies to simplify delivery of WAN services to branch offices. Software based virtualization enables network abstraction that results in simplification of network operations.

The costly branch network using MPLS cloud is replaced by Cloud based services which are connected to the branches using secure overlay networks. This reduces the cost of the high complexity branch deployments.
SD-WAN in a nutshell:
✓Virtualizes the network
✓Enables a secure overlay
✓Simplifies services delivery
✓Provides interoperability
✓Leverages cost effective hardware
✓Supports automation with business policy framework
✓Monitors usage and performance
✓Supports interoperable and open networking
✓Enables managed services

Branch networking can automate deployment over private networks, broadband internet and LTE.

According to the IHS Technology Data Center Network Equipment Quarterly Market Tracker report, there was a total of $38.5 million in SD-WAN revenue during the first quarter of 2017.

Viptela had a strong lead with $7.7 million in revenue, or 21 percent of the total market share; VeloCloud claimed $4.9 million in revenue, or 14 percent of the market; and Talari Networks brought in $3.8 million in revenue — 11 percent of the market share for the quarter, according to the report.

As network pros rely more and more on SD-WAN to streamline connections among enterprise sites, the market for this technology will balloon from $225 million in 2015 to $1.19 billion by the end of 2017, according to IDC.

Over the next five years, SD-WAN sales will grow at a 69% compound annual growth rate, hitting $8.05 billion in 2021, according to IDC’s Worldwide SD-WAN Forecast, 2017–2021.

OpenFlow prospects

OpenFlow was adopted as protocol of communication between SDN controllers and SDN compliant DP switches. This strategy was adopted to disaggregate the control plane from data plane giving the end user more programmability using SDN based networks.

Service provider deployment of SDN vs Enterprise deployment of SDN         

https://www.networkcomputing.com/networking/sdn-time-move-gartner-says/927734697

In the enterprise, that approach garnered a lot of interest, but ultimately limited acceptance, the analysts said, estimating less than 2,000 deployments that meet the original architectural requirements, mostly in Japan. The story's different in the service provider market, where OpenFlow, which became synonymous with SDN, "gained significant traction," according to Gartner.

Among the many reasons for the tepid enterprise adoption cited by Gartner: The conservative nature of networking buyers, a lack of immediate business drivers, and the market power of incumbent vendors that had a vested interest in protecting their position.

The overall data center network equipment market includes Ethernet switches, bare metal, application delivery controllers (ADCs), and SD-WAN revenue.

While investment in physical infrastructure continues to drive network equipment growth in the short term, IHS Markit expects this to slow down this year (2018) and next as companies move from on-premises data centers to the cloud. This will mean fewer — but higher capacity — servers, reducing the need for data center Ethernet switch ports along with the move to virtual ADCs.

Data center network equipment revenue totaled $13.7 billion in 2017, a 13 percent increase over the previous year, according to IHS Markit’s latest numbers. The analyst firm forecasts the market will grow to $19.6 billion by 2022.

The ongoing shift to the cloud not only moves network equipment out of the enterprise data center, but also requires less equipment, as the cloud represents data center consolidation on a wide scale.” The new data center network equipment report also projects SD-WAN revenue, which hit $444 million for the full-year 2017, will reach $3.6 billion by 2022. The next wave for SD-WAN includes increased analytics, with artificial intelligence (AI) and machine learning (ML) providing multi-cloud connectivity,

Leader's Mindset

• Do not be limited to your direct responsibilities in your work. Extend your sphere to enable / facilitate other teams if you have the bandwidth. This will ensure you remain connected to other teams even if they are not direct reportees, grow in your work and in the process be an enabler for others.
• Work closely with your team members to help identify areas where you can help them excel. Be a part of their success.
• Learnt to restrain your frustration and anger. It never helps other than aggravating situation. If faced with a challenging situation where things aren't moving as you expect, think calmly and you will have a way around the problem without souring relationship.
• Ignore small things which you are likely to forget in due course of time. Do not attach too much importance to trivial things and loose your sleep.
• Good communication is very important for a leader. Before any discussion, try to role play and anticipate the mind of the person with whom you are going to converse and plan your responses accordingly. People do not like to converse with colleagues who are shallow in their discussion points.
• Its also important to ensure that communication brings out the right meaning as was meant to be communicated.
• Know the processes well and make sure you adhere to them. A good leader is expected to follow processes or improve upon them.
• Be always prepared for a meeting well before hand with concrete points and responses to possible questions that may get asked.
• If you do not get criticised in your profession it will mean that your profession is not important enough. In any path of life, if you get accolades be also prepared for brickbats. It comes with the package. 
• Learn to back your instincts. Always formulate an opinion regarding the things around you.

Cloud Services ...

Users:
8,000 companies in India that have already boarded the AWS ship, including large enterprises such as Tata Motors, Reliance Entertainment, NDTV, Narayana Health, Macmillan India, EROS International, Malayala Manorama and Sony Entertainment.

Competition:
Amazon's aggressive pricing has also forced its competitors to make similar price cuts, making cloud computing more compelling for Indian enterprises. And competition is increasing in the cloud market. IBM has been spending millions of rupees advertising its Softlayer cloud as it tries to challenge AWS' dominance while Microsoft has indicated plans to set up a data centre in India to push its cloud offerings in the country.

Issues:
-territorial issues in holding the data in the country
-large-scale adoption of cloud among Indian enterprises is still some time away. "It will take another two or three years before corporates start using the public cloud in a strategic manner. Part of that is because of the ageold concerns — network connectivity, availability and even data privacy," Mishra said. "But that could change as public cloud providers start investing in data centres in India."

The Fast ends. Its moral victory for the People...

The Anna Hazare fast finally ended today after 288 hours. Herculean effort and all for the country. Kudos to the man for his steadfast resolution and for galvanizing the people for this movement.

As per Pranab Mukherjee's opening speech in Parliament yesterday, there were 40 points in Anna Hazare's Jan Lok Pal bill. Out of those 40 points, there was consensus with the government on 20 of them. On 7 points there was consensus with some editing and another 7 points had agreement between the two parties in principle. There were 6 points which faced differences between the two sides. These points were:

1. Bringing the PM under the Lok-Pal.

2. Bringing the conduct of the MPs inside the house under the purview of Lok-Pal.

3. Bringing the judiciary under the purview of Lok-Pal

4. Creating of Lok-Ayuktas (in states) as part of the Lok-Pal bill.

5. Bringing the lower bureaucracy under the Lok-Pal ambit.

6. Creating a citizen's charter for addressing people'e grievances.

After several rounds of discussion between Anna's team and the Govt., and also judging the opinion of the largest opposition party, the Govt. began to concede on bringing the PM under the Lok-Pal ambit.

It was also apparent that conduct of MPs inside the house would remain outside the scrutiny of the Lok-Pal since all parties unanimously opposed it.

As enshrined in our constitution, Judiciary is independent of the Legislature and everyone was of the opinion that  however corrupt the judiciary might be, it would be wrong to bring the judiciary under the Lok-Pal for it would make the system devoid of the proper checks and balances that are required. Hence, unanimous opinion was to make the judiciary account through judicial accountability bill.

Point nos. 4,5,6 remained the sticky issues on which there was no considerable agreement and the opinion of the various political parties on this issue was also unclear. Anna wanted a resolution on the sticky points to be passed in Parliament so that the opinion of each of the political parties comes out in the open. Anna had kept the condition of breaking his fast only after the parliament passed a resolution agreeing to consider all the 3 points mentioned above.

After 8 hours of debate in Parliament on the 27th-Aug, it was clear that the Govt and the largest opposition party-BJP along with some of the other parties were in agreement to pass a resolution, agreeing on all the 3 sticky points. The final content of the resolution was presented to Anna Hazare paving the way for the fast to end after a 288 hours marathon.

The draft is now going to go through the Standing Committee before its passed by the Parliament. How long will that take, what would be final contents of the Bill and whether the Govt will rise above petty bickering to present a strong Lok-Pal bill is something that time will tell.

Let people's voices be heard and the country grow stronger into a more vibrant democracy in its true sense.
