Now we can cross the Atlantic 100,000x faster

IT Strategy 101: The network is an afterthought

My company has agreed on a cloud first strategy, but our WAN is designed for connecting our offices and data centers, not cloud applications. “

bandwidth has little impact on

improving application performance

Reducing latency has a significant

impact on improving application

The network is working just fine

Meanwhile, at the border…

SD-WAN – the best thing since…

IBM Cloud

26

Understands real-time traffic conditions

27

Makes intelligent decisions

28

Selects the optimal route

29

Application performance is now visible

30

But its not all plain sailing, there are icebergs ahead…

31

Access is key

32

a) Enforced private network last mile from legacy players

33

b) Or the choice of thousands from a top 5 Internet provider?

So…. what do the analysts say?

47

The combination of cloud and edge poses significant organizational, culture and skills challenges:

- Cloud and Edge architects needed

- Networking and Connectivity are critical

- Security must extend to all cloud and distributed systems

- Data ownership?

- How will AI/ML impact the cloud/edge environment?

The Agile Network –

Software-defined Infrastructure vs. Traditional Telco

Application aware

Adapts in real-time

Accessible via any access

Internet centric but not restrained

Cloud integrated

Secured everywhere

Flexible & on-demand

Controlled by policy
