Our Next Meeting - Wednesday June 5, 2019

Deploying Enterprise Application Services in Kubernetes

To deploy containerized applications based on microservices architecture in production, application services such as load balancing, application security and analytics need to be modernized. With the growing adoption of container ecosystems, Kubernetes and OpenShift are becoming popular choices for enterprises today.

Kubernetes is a portable, extensible open-source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely available.

Google open-sourced the Kubernetes project in 2014. Kubernetes builds upon a decade and a half of experience that Google has with running production workloads at scale, combined with best-of-breed ideas and practices from the community.

Avi Networks' Multi-Cloud Application Services extend application delivery for K8s clusters to cloud and on-prem data centers, making migration across various ecosystems easier. This session will look at the bigger picture by exploring all the components necessary to deploy a production-ready container-based application.


- Review how containers and microservices have changed traditional application delivery
- Understand the 'North-South' and 'East-West' nature of microservices
- Learn how Avi fits into the k8s ecosystem - working either alongside or replacing Kube-proxy
- Ensure application availability and visibility with Avi's software load balancer fabric
- Integration into CI/CD Pipelines

Note: To be better prepared for Gary's presentation, please see the following overview and additional detail on Kubernetes and containers:

DFWCUG welcomes Avi Networks as our monthly

meeting sponsor for June 2019



Enterprises seek public-cloud-like agility. However, appliance-based load balancers can’t meet the needs of cloud-native applications in modern data centers. We built Avi Networks to match the application services needs of these dynamic environments that go well beyond load balancing. Avi eliminates overspending and over-provisioning and elevates load balancing by taking advantage of the strategic position of load balancers (in the path of application traffic) to deliver application insights that have never before been possible. The Avi Vantage Platform delivers elastic and programmable application services on standard x86 servers, VMs, or containers on-premises or in the cloud.


Our Last Meeting - Wednesday May 1, 2019


Securing the Datacenter with Micro-Segmentation

Data centers have become drastically more complex in the last decade, and it’s only getting worse. Technology advances daily, and by the time IT engineers finish an implementation, it’s already time to upgrade. Developers are deploying and upgrading applications faster than anyone could have ever imagined. We no longer have a data center filled with bare metal servers, in a single data center, doing single tasks. Instead, we have virtualized workloads doing multiple things, spread across various geographical locations; sometimes being hosted across multiple providers, such as AWS or Azure. This is in addition to our on-prem workloads.


In all this, attackers are becoming more and more advanced. Threats are constant, and they aren’t going away. By compromising a single host, hackers are able to move freely throughout our data centers, without the fear of containment or rapid response. We cannot continue to deploy 1990’s concepts and technologies and expect to not be compromised at some point. We need to start thinking outside of the box and deploy solutions that will not only baseline and learn our environments, but react quickly when things are behaving abnormally.


JP Cedeno, Technical Solutions Architect - Cisco Systems, CCIE #47408

JP started his career 19 years ago as a desktop support administrator. He quickly evolved his skills and became a network systems engineer, primarily dealing with Microsoft and VMware products. His projects included building and migrating large scale VMware clusters along with doing Active Directory, Exchange, and MSSQL upgrades and migrations.


JP was eventually promoted to a managerial position overseeing the enterprise infrastructure group. It was his job, and the job of his team, to maintain all systems within the data center. At this point in his career, JP had achieved his CCNA and CCNP in routing and switching. As a manager, he felt it was his duty to better support his team and achieve his CCIE.


After passing his CCIE lab exam in 2015, he spent a little over 1 year redesigning iPexpert's CCIE R&S bootcamp. He moved on to join Cisco as a Technical Solutions Architect, and also formed his own company to provide the best Cisco training on the market. XtremeIE currently provides high quality video training to hundreds of engineers looking to advance their skill set and become a true expert.
