The mad dash to connect virtually every noun to the internet or the Internet of Things is creating a massive M2M network for all the devices, systems, sensors and actuators to connect & communicate on the Internet. With that, they need a communications protocol to understand each other. One of those is Message Queue Telemetry Transport (MQTT). MQTT is a “subscribe and publish” messaging protocol designed for lightweight machine-to-machine (or IoT) communications. In this episode of Lightboard Lessons, I light up how MQTT works. ps Related: IoT Ready Infrastructure IoT Effect on Applications IoT Influence on Society What are These "Things?

Deploy BIG-IP VE in Microsoft Azure Using an ARM Template

Azure Resource Manager (ARM) templates allow you to repeatedly deploy applications with confidence. The resources are deployed in a consistent state and you can easily manage and visualize resources for your application. ARM templates take the guesswork out of creating repeatable applications and environments. Deploy and deploy again, consistently. Let’s walk through how to deploy a simple, single-NIC configuration of BIG-IP VE in Microsoft Azure using an ARM template. First, go to the F5 Networks Github site where we keep our supported templates. There are other community-based templates at www.github.com/f5devcentral if needed but for F5 supported templates, go to the F5 Networks site.   To view Azure templates, click f5-azure-arm-templates. In that folder you’ll see experimental and right under that is supported (the one you want). Then click on the standalon... (more)

Q/A with Betsson’s Patrik Jonsson – DevCentral’s Featured Member for April

Patrik Jonsson lives in Stockholm with his wife and son and works as a network engineer for a company providing online casino games across the world. Outside work, he likes to spend time with his family, play around with his home VMware lab and enjoys watching movies. He also loves travelling and having a beer with friends. Patrik is also a 2017 DevCentral MVP and DevCentral’s Featured Member for April! DevCentral got a chance to talk with Patrik about his work, life and his project the BIG-IP Report. DevCentral: You’ve been a very active contributor to the DevCentral community and wondered what keeps you involved? Patrik: One of the best, and fun ways to learn new things is to take on problems, or discussions presented by fellow technicians. It forces you to continuously challenge what you think you know and keeps your knowledge up to date. In addition, when I ne... (more)

Lightboard Lessons: Service Consolidation on BIG-IP

In this Lightboard Lesson, I light up many of the services you can consolidate on BIG-IP.   ps ... (more)

What Is a Proxy? | @DevOpsSummit #Agile #DevOps #ContinuousDelivery

The term ‘Proxy’ is a contraction that comes from the middle English word procuracy, a legal term meaning to act on behalf of another. You may have heard of a proxy vote. Where you submit your choice and someone else votes the ballot on your behalf. In networking and web traffic, a proxy is a device or server that acts on behalf of other devices. It sits between two entities and performs a service. Proxies are hardware or software solutions that sit between the client and the server and does something to requests and sometimes responses. The first kind of proxy we’ll discuss is a half proxy. With a Half-Proxy, a client will connect to the proxy and the proxy will establish the session with the servers. The proxy will then respond back to the client with the information. After that initial connection is set up, the rest of the traffic with go right through the proxy... (more)

Social Login to Enterprise Apps using BIG-IP & OAuth 2.0

Password fatigue is something we’ve all experienced at some point. Whether it’s due to breaches and the ever present, ‘update password’ warnings, the corporate policy of a 90-day rotation or simply registering for a website with yet another unique username and password. Social login or social sign-in allows people to use their existing Google, Twitter, Facebook, LinkedIn or other social credentials to enter a web property, rather than creating a whole new account for the site. These can be used to authenticate, verify identity or to allow posting of content to social networks and the main advantage is convenience and speed. With v13, BIG-IP APM offers a rich set of OAuth capabilities allowing organizations to implement OAuth Client, OAuth Resource Server and OAuth Authorization Server roles to implement social logins. Let’s look at BIG-IP’s capabilities (from the us... (more)

High Availability Groups on BIG-IP

High Availability of applications is critical to an organization’s survival. On BIG-IP, HA Groups is a feature that allows BIG-IP to fail over automatically based not on the health of the BIG-IP system itself but rather on the health of external resources within a traffic group. These external resources include the health and availability of pool members, trunk links, VIPRION cluster members or a combination of all three. This is the only cause of failover that is triggered based on resources outside of the BIG-IP. An HA group is a configuration object you create and assign to a traffic group for devices in a device group. An HA group defines health criteria for a resource (such as an application server pool) that the traffic group uses. With an HA group, the BIG-IP system can decide whether to keep a traffic group active on its current device or fail over the traff... (more)

The #IoT and DNS | @ThingsExpo #BigData #IoT #M2M #DigitalTransformation

JANUARY 8, 2014 02:00 PM EST When we talk about the impact of BYOD and BYOA and the Internet of Things, we often focus on the impact on data center architectures. That's because there will be an increasing need for authentication, for access control, for security, for application delivery as the number of potential endpoints (clients, devices, things) increases. That means scale in the data center. What we gloss over, what we skip, is that before any of these "things" ever makes a request to access an application it had to execute a DNS query. Every. Single. Thing. Maybe that's because we assume DNS can handle the load. So far it's done well. You rarely, if ever, hear of disruptions or outages due directly to the execution of DNS. Oh, there has been some issues with misconfiguration of DNS and of exploitation of DNS (hijacking, illicit use in reflection attacks, et... (more)

Lightboard Lessons: The BIG-IP Profiles

BIG-IP can manage application-specific network traffic in a variety of ways, depending on the protocols and services being used. On BIG-IP, Profiles are a set of tools that you can use to intelligently control the behavior of that traffic. In this Lightboard Lesson, I light up the BIG-IP Profiles. What they are, what they do and why you should care. ps Related: Lightboard Lessons: BIG-IP Basic Nomenclature Lightboard Lessons: Device Services Clustering ... (more)

Protecting API Access with BIG-IP using OAuth

As more organizations use APIs in their systems, they’ve become targets for the not-so-good-doers so API Security is something you need to take seriously. Most APIs today use the HTTP protocol so organizations should protect them as they would ordinary web properties. Starting in v13, BIG-IP APM is able to act as an OAuth Client, OAuth Resource Server and OAuth Authorization Server. In this example, we will show how to use BIG-IP APM to act as an OAuth Resource Server protecting the API. In our environment, we’ve published an API (api.f5se.com) and we’re trying to get a list of departments in the HR database. The API is not natively protected and we want APM to enable OAuth protection to this API. First, let’s try an unauthenticated request. You can see we get the 401 Unauthorized response which is coming from the BIG-IP. In this instance we’re only sending 3 header... (more)

What Is Virtual Desktop Infrastructure | @CloudExpo #VDI #Cloud #DataCenter

What is VDI? Imagine not having to carry around a laptop or be sitting in a cubicle to access your work desktop applications. Virtual desktop infrastructure (VDI) is appealing to many different constituencies because it combines the benefits of anywhere access with desktop support improvements. Employees typically use a wide range of mobile devices from laptops to tablets and from desktops to smartphones are being used. The diversity of these mobile devices and the sheer number of them in the workplace can overwhelm IT and strain your resources. Desktop Virtualization centralizes sets of desktops, usually in a data center or cloud environment, and then provide access to your employees whether they are in the office, at home or mobile.  VDI deployments virtualize user desktops by delivering them to distinctive endpoint devices over the network from a central locatio...
