Part 2: The modern IT network encounters a lot of twists and turns on its way to high performance and user satisfaction

All About the Metrics: Part 2, Network Metrics
By Christine Cignoli

The modern IT network encounters a lot of twists and turns on its way to high performance and user satisfaction. The humble network, which for a long time was fairly straightforward, is now a complicated infrastructure component that requires careful management and monitoring. Private and public network topologies are much more diverse these days, so that app delivery takes many twists and turns through paths, protocols and configurations along various networks, whether LAN, WAN or cloud.

As the network is being pushed front and center, according to IDG's 2016 State of the Network study, network teams have to collaborate more with the greater IT realm and the organization. The metrics involved have gotten more important, and more complicated, as the network has gotten more complex. And, as networks are more complex, they also have to start working as part of a bigger team. The network can't exist in isolation anymore. Instead, it has to enable the rest of the infrastructure components to do their jobs.

End-user experience has become a high priority in enterprise computing, and the network plays a major part in that. IDG's study found that respondents see both the challenges and rewards of cloud. Seven out of ten of IT pros surveyed said the cloud will add complexity for the networking team, and six out of ten said it would alter the structure of the network team. But a majority also responded that cloud computing will help the networking team gain tech knowledge and become more valuable to the business. That reflects both the challenges and opportunities now faced by network teams.

The Network Metrics That Matter

The handy network metrics you've been gathering all these years don't have to lose their value as the focus and goals of IT services change. You can use those metrics in the troubleshooting process to solve end-user problems, and, even better, to get ahead of user complaints proactively. Gartner recommends using a combination of both quantitative and qualitative metrics in the troubleshooting process to get to the root of issues.

There are a few key network metrics we recommend to tie network performance to end-user experience (and find here the application performance metrics we recommend). Start with these as you're looking for the right mix of metrics.

Link Latency and Round-Trip Time: These numbers will show you which path in the network is causing performance delays. These metrics have become especially important as the types and numbers of networks have increased. Link latency and round-trip time apply to both public and private networks, which is useful in a hybrid environment.

Jitter: This network metric reflects the time differences in packets arriving at their destination. In a modern context, it can explain inconsistent user experience measurements across multiple applications.

Throughput: This is a basic measure of how much information a system can process in a certain amount of time, and applies across many systems. It's a key application metric to measure for better end-user experience. Identifying throughput problems can help IT get to the root of network-related issues as well.

Available Capacity: Measure this number over time, as it can identify user problems stemming from improper resource allocation.

Bandwidth Consumed: Keep an eye on this metric and any changes over time to get a better understanding of the network resources available to the application in question.

Other metrics related to infrastructure health are involved in improving end-user experience. Database response times can reveal latency issues for certain functions, and you should filter by geographic area to reveal the impact of local network problems on those users.

Using network metrics to benefit your end users can lead to better, faster problem solving, more uptime, and right-sized resources and bandwidth. Which of these metrics are you using?

The goal of Continuous Testing is to shift testing left to find defects earlier and release software faster. This can be achieved by integrating a set of open source functional and performance testing tools in the early stages of your software delivery lifecycle. There is one process that binds all application delivery stages together into one well-orchestrated machine: Continuous Testing. Continuous Testing is the conveyer belt between the Software Factory and production stages. Artifacts are moved from one stage to the next only after they have been tested and approved to continue. New code submitted to the repository is tested upon commit. When tests fail, the code is rejected. Subsystems are approved as part of periodic builds on their way to the delivery stage, where the system is being tested as production ready. The release process stops when tests fail. The key is to shift test c...
In IT, we sometimes coin terms for things before we know exactly what they are and how they’ll be used. The resulting terms may capture a common set of aspirations and goals – as “cloud” did broadly for on-demand, self-service, and flexible computing. But such a term can also lump together diverse and even competing practices, technologies, and priorities to the point where important distinctions are glossed over and lost.
Most companies are adopting or evaluating container technology - Docker in particular - to speed up application deployment, drive down cost, ease management and make application delivery more flexible overall. As with most new architectures, this dream takes a lot of work to become a reality. Even when you do get your application componentized enough and packaged properly, there are still challenges for DevOps teams to making the shift to continuous delivery and achieving that reduction in cost and increase in speed.
Enterprise architects are increasingly adopting multi-cloud strategies as they seek to utilize existing data center assets, leverage the advantages of cloud computing and avoid cloud vendor lock-in. This requires a globally aware traffic management strategy that can monitor infrastructure health across data centers and end-user experience globally, while responding to control changes and system specification at the speed of today’s DevOps teams. In his session at 20th Cloud Expo, Josh Gray, Chief Architect at Cedexis, covered strategies for orchestrating global traffic achieving the highest-quality end-user experience while spanning multiple clouds and data centers and reacting at the velocity of modern development teams.

DevOps is under attack because developers don’t want to mess with infrastructure. They will happily own their code into production, but want to use platforms instead of raw automation. That’s changing the landscape that we understand as DevOps with both architecture concepts (CloudNative) and process redefinition (SRE). Rob Hirschfeld’s recent work in Kubernetes operations has led to the conclusion that containers and related platforms have changed the way we should be thinking about DevOps and controlling infrastructure. The rise of Site Reliability Engineering (SRE) is part of that redefinition of operations vs development roles in organizations.
All organizations that did not originate this moment have a pre-existing culture as well as legacy technology and processes that can be more or less amenable to DevOps implementation. That organizational culture is influenced by the personalities and management styles of Executive Management, the wider culture in which the organization is situated, and the personalities of key team members at all levels of the organization. This culture and entrenched interests usually throw a wrench in the works because of misaligned incentives.
SYS-CON Events announced today that Datera, that offers a radically new data management architecture, has been named "Exhibitor" of SYS-CON's 21st International Cloud Expo ®, which will take place on Oct 31 - Nov 2, 2017, at the Santa Clara Convention Center in Santa Clara, CA. Datera is transforming the traditional datacenter model through modern cloud simplicity. The technology industry is at another major inflection point. The rise of mobile, the Internet of Things, data storage and Big Data are challenging the existing design patterns of the Data Center. The increase in complexity of managing legacy systems alongside new systems is beyond the ability of most IT departments. This leads to multiple tiers of storage and high economic costs, during a time in which IT is expected to do more with less.
Given the popularity of the containers, further investment in the telco/cable industry is needed to transition existing VM-based solutions to containerized cloud native deployments. The networking architecture of the solution isolates the network traffic into different network planes (e.g., management, control, and media). This naturally makes support for multiple interfaces in container orchestration engines an indispensable requirement.
