Have you used a public cloud? The experience as a developer is truly fantastic. Enter your credit card information and go. Need more resources? Click. Tear down a server and start over? Click. Want APIs for granular access to configure and automate every part of your deployments exactly the way you need them? No problem. Built-in integration with the modern tools and platforms you’re using? Of course.
Traditional IT vs Cloud
Compare that to traditional infrastructure where it takes phone calls or tickets, approvals, and many different platforms that typically aren’t integrated just to get access to servers. Automation is difficult or impossible. Moving fast as a developer just isn’t something you can do. You spend your time wrangling the infrastructure instead of building your app.
The public cloud experience for a developer is liberating. It’s easy, fast, and predictable. It helps them deliver on their promises to the business by removing any obstacles to the resources they need.
Smart companies are freeing their development teams from traditional IT models and helping them move fast by taking advantage of cloud.

Over the last few years, we’ve heard a lot about ways of designing new software applications. Out of this, we’ve heard a lot about “Microservice Architecture” as a way to design these applications as individual components to make up an actual application. Refer back to this recent blog regarding the impact of microservices and containers on application enablement for the enterprise. Many attempts to define the architecture were undertaken, and in general the complexities of software platform and different viewpoints on the underlying components necessary have not resulted in an agreed solution.

Cisco has developed a plug-in to integrate the ASR 1000 Series Router
(ASR1K) into OpenStack to offload L3 capabilities on to dedicated routing hardware. The plug-in was demonstrated at Cisco Live in a Proof-of-Concept environment. We are planning demos of a Cloud solution based on the ASR1k plug-in at the OpenStack Summit in Vancouver. The plug-in is considered open source and will be submitted upstreamed into OpenStack. It will also be available from Cisco’s Neutron Tech-Preview repository
OpenStack offers a reference software implementation for Layer 3 functionality. Routing, static NAT (Floating IPs) and dynamic NAT/SNAT (VM “Internet” access) are handled by the l3agent that runs part of the neutron component. The L3 agent relies on Linux IP Tables to define forwarding rules. With that comes a critical scalability issue as Linux IPTables has inherent scaling shortcomings. For highly-scalable clouds with many route and NAT operations, this becomes a serious bottleneck.
Cisco offers the ASR1K routing platform to be used in Data Centers typically for WAN edge operations. It performs NAT and L3 forwarding in hardware and provides L3 high-availability (HSRP). The ASR Config Agent builds upon the same technology utilized for the integration of the Cisco Cloud Services Router (CSR1000v
) into OpenStack.

If you are involved in designing, supporting or managing a data center, you will undoubtedly rely on technical support services from one or more vendors. Running your data center, there is always the risk of a hardware failure or being impacted by a software defect. While relatively rare, hardware does occasionally fail unfortunately. However you undoubtedly have technical support in place to deal with such problems. You may have invested in a few extra switches as backup, you may also have failover mechanisms in place. Almost certainly you will have a support contract in place with your Cisco partner or with Cisco, so you have break/fix expertise on tap for when something goes wrong. This is critical support for your business, no debate from me.
Engineer Under Stress!
Now, arguably the most important resource you have in your data center is not so much individual switches, routers or servers. It’s your engineers, those who design and support your data center. If they have a problem, where and how do they get help? Who helps them when they are stretched? When business pressures are telling? Of course, their colleagues and managers can and will help. Where, however, can they tap into additional sources of expertise so that they can become even more productive for you? This is where Cisco Optimization Services come in – including our award-winning Cisco Network Optimization Service (or “NOS” for short), Collaboration Optimization Service, and the one I’m involved with, Cisco Data Center Optimization Services.
