Lightboard Lessons: What is BIG-IP APM?

In this Lightboard, I light up some lessons on BIG-IP Access Policy Manager. BIG-IP APM provides granular access controls to discreet applications and networks supporting 2FA and federated identity management. You can also check out Chase’s written article What is BIG-IP APM? ps ... (more)

I’ve Successfully Failed the F5 Certification 201-TMOS Administration Exam

Yup, you read that right. I did not pass the F5 Certified BIG-IP Administrator test I took while at F5 Agility 2017. And I’m not ashamed since it was a challenging test and I will be trying again. Sure, I went through Eric Mitchell’s (F5er) comprehensive 201 Certification Study Guide along with the TMOS Administration Exam Blueprint. However, I probably should have taken more time ON a BIG-IP messing around…especially for tmsh commands…which is where, I believe, I got tripped up. This is key. Reading and memorizing commands along with some practicing can only get you so far. Doing it regularly is what’s needed. This is a key feature of the exams, particularly as you move up the exam expertise. The exams are designed to test real knowledge and experience, not if you can cram the night before. Pretty sure my errors came with tmsh and the UCS upgrade questions since I ... (more)

DevCentral Cloud Month – Week Four

What’s this week about? Ready for another week of Cloud Month on DevCentral? Suzanne, Hitesh, Greg, Marty and Lori are ready! Last week we looked at services, security, automation, migration, Ansible and other areas to focus on once you get your cloud running. We also had a cool Lightboard Lesson explaining BIG-IP in the public cloud. This week we go deeper into areas like high availability, scalability, responsibility, inter-connectivity and exploring the philosophy behind cloud deployment models. Now that we’re half-way through Cloud Month, I thought it’d be fun to share a little bit about our authors. Suzanne Selhorn is a Sr. Technical Writer with our TechPubs team. Our Technical Communications team are responsible for many of the deployment guides you use and are also the creators of some of the awesome step-by-step technical videos featured on DevCentral’s You...

DevCentral Cloud Month – Week Three

What’s this week about? We hope you’re enjoying DevCentral’s Month thus far and Suzanne, Hitesh, Greg, Marty and Lori ready to go again this week. Last week we got you deployed in AWS and Kubernetes, learned the basics of Azure, got knee-deep in Cloud/Automated architectures and celebrated SOA’s survival. Now that your cloud is installed and running, this week we look at things like security, migration, services, automation and the challenges of data management. Monday, Suzanne will help you secure your new AWS application with a F5 WAF; Tuesday, Hitesh will explore the Services Model for cloud architectures; Wednesday, Greg gets into Deployment Scenarios for BIG-IP in Azure; if you thought 24 minutes was quick, on Thursday Marty shows how to deploy an app into Kubernetes even faster; and Lori and her infinite cloud wisdom, wonders if the technical and data integrat...

DevCentral Cloud Month – Week Two

What’s this week about? You got a mini taste of DevCentral’s Cloud Month last week and week two we really dig in. This week we’re looking at Build and Deployment considerations for the Cloud. The first step in successfully deploying in a cloud infrastructure. Starting today, Suzanne and team show us how to deploy an application in AWS; On Wednesday, Greg, harking the Hitchhiker’s Guide, explains Azure’s Architectural Considerations; Marty uncovers Kubernetes concepts and how to deploy an application in Kubernetes this Thursday; on #Flashback Friday, Lori takes us down memory lane wondering if SOA is still super. Filling my typical Tuesday spot, Hitesh reveals some foundational building blocks of F5’s cloud/automated architectures. These will help get you off the ground and your head in the clouds, preferably Cloud Nine. Enjoy! ps Related: 5 steps to building a c... (more)

Create a BIG-IP HA Pair in Azure

Use an Azure ARM template to create a high availability (active-standby) pair of BIG-IP Virtual Edition instances in Microsoft Azure. When one BIG-IP VE goes standby, the other becomes active, the virtual server address is reassigned from one external NIC to another. Today, let’s walk through how to create a high availability pair of BIG-IP VE instances in Microsoft Azure. When we’re done, we’ll have an active-standby pair of BIG-IP VEs. To start, go to the F5 Networks Github repository. Click F5-azure-arm-templates. Then go to Supported>ha-avset and there are two options. You can deploy into an existing stack when you already have your subnets and existing IP addresses defined but to see how it works, let’s deploy a new stack. Click new stack and scroll down to the Deploy button. If you have a trial or production license from F5, you can use the BYOL option but i... (more)

DevCentral’s Featured Member for July – Vosko Networking’s Niels van Sluis

For almost two years Niels van Sluis has worked as a Security Engineer for Vosko Networking. Vosko’s security team focuses on supporting security solutions from various vendors like F5, Check Point, Cisco and RSA. Niels focuses is on F5 BIG-IP and Check Point. He started his professional career about 20 years ago in the ISP industry as an Unix Administrator, and switched to the public healthcare sector around 2001. In more recent years, he’s moved more towards working on network security and design. Apparently, having a Unix background helps a lot when working with modern security devices, since most of them are running on some flavor of Unix. When not working or spending time on DevCentral, he likes to travel, visit historic places and enjoy nature. And Niels is DevCentral’s Featured Member for July!

BIG-IP VE on Google Cloud Platform

Hot off Cloud Month, let’s look at how to deploy BIG-IP Virtual Edition on the Google Cloud Platform. This is a simple single-NIC, single IP deployment, which means that both management traffic and data traffic are going through the same NIC and are accessible with the same IP address. Before you can create this deployment, you need a license from F5. You can also get a trial license here. Also, we’re using BIG-IP VE version 13.0.0 HF2 EHF3 for this example. Alright, let’s get started. Open the console, go to Cloud Launcher and search for F5. Pick the version you want. Now click Launch on Compute Engine. I’m going to change the name so the VM is easier to find… For everything else, I’ll leave the defaults. And then down under firewall, if these ports aren’t already open on your network, you can open 22, which you need so you can use SSH to connect to the inst... (more)

DevCentral Cloud Month Wrap

Is it the end of June already? At least it ended on a Friday and we can close out DevCentral’s Cloud Month followed by the weekend! First, huge thanks to our Cloud Month authors: Suzanne, Hitesh, Greg, Marty and Lori. Each delivered an informative series (23 articles in all!) from their area of expertise and the DevCentral team appreciates their involvement. We hope you enjoyed the content as much as we enjoyed putting it together. And with that, that’s a wrap for DevCentral Cloud Month. You can check out the original day-by-day calendar and below is each of the series if you missed anything. Thanks for coming by and we’ll see you in the community.

Cloud Month on F5 DevCentral

#DCCloud17 The term ‘Cloud’ as in Cloud Computing has been around for a while. Some insist Western Union invented the phrase in the 1960s; others point to a 1994 AT&T ad for the PersonaLink Services; and still others argue it was Amazon in 2006 or Google a few years later. And Gartner had Cloud Computing at the top of their Hype Cycle in 2009. No matter the birth year, Cloud Computing has become an integral part of an organization’s infrastructure and is not going away anytime soon. A 2017 SolarWinds IT Trends report says 95% of businesses have migrated critical applications to the cloud and F5’s SOAD report notes that 20% of organizations will have over half their applications in the cloud this year. It is so critical that we’ve decided to dedicate the entire month of June to the Cloud. We’ve planned a cool cloud encounter for you this month. We’re lucky to have... (more)
