* Yes, I do understand that Lambda@Edge will provide a completely different level of scale and performance, and is an industrialised managed offering. None the less, what’s described below could serve many use cases just fine. 😉
With that, on to it.
There’s no point arguing that Single Page Apps (SPAs) are in vogue. One of the approaches to SPAs is to move business logic into the client, and leverage a range of API-based services to provide needed server-side functionality. Here’s a very good argument presented on this topic: Joe Emison – 10X Product Development.
A side effect of following this pattern is your SPA code ends up on a server that only knows how to serve your static client content (html / js / css / images). This may present a problem when you try to integrate your SPA with another stand-alone application, for example, blog hosted by WordPress.
Let’s have a look in a bit more detail, followed by what can be done about it.
With Hardware VTEP being implemented in, well, hardware, how things work depends on capabilities of the underlying chipset. This means that when we design solutions using these products, we need to keep these capabilities in mind and configure things accordingly.
In this short post I’ll cover a situation we’ve encountered at one of our customers where things “should” have worked but didn’t, and what was the reason for that.
Last time we’ve talked about the concept of Infrastructure as Code (IaC), and introduced two most prominent tools in the space, AWS CloudFormation and Hashicorp Terraform.
In this post, we’ll have a look at an AWS CloudFormation template that you can use to deploy a cluster of 2 x Brocade Virtual Traffic Managers with WAF into a new AWS VPC; what makes up that template; and how it all works.
We will take things quite slowly here. Some basic understanding of automation and/or scripting/programming will help, but not strictly necessary.
If on other hand you’re already well-versed in AWS CloudFormation but still interested in automating deployment of Brocade Virtual Traffic Managers in AWS, feel free to jump straight to the GitHub repo, and optionally read the vADC EC2 Instances section below.
Please note that this is work in progress and the code you’ll find there has no official support at this time, but rest assured, it is coming! 🙂
This post is next in series on using HW VTEPs with NSX-v. You can find earlier posts here: 1, 2, and 3.
Today we’ll look at a couple of choices you’ll need to make when deploying Brocade’s HW VTEP, and then check if our configuration is correct before linking it with NSX-v next time.
In a couple of previous blog posts, we’ve looked at the use cases for HW VTEPs. Now, let’s start digging a bit deeper.
In this instalment, we’ll have a look at what things you need to think about when planning your Hardware VTEP deployment. While I’ll be using Brocade VCS as the HW VTEP for this post, some of this info should be applicable to other Vendors’ solutions.
Applications are lifeblood of a modern business. This means that IT groups everywhere are looking for ways to develop, test, and deploy applications quicker, while reducing risk of mistakes and thus potential defects and security issues.
In this post, we’ll have a quick look at how an approach called “Infrastructure as Code” can help.
I am a long time user of Apple’s Airport Extreme base stations. I loved pretty much everything about them – compact design, lack of protruding external antennae, stable connectivity, ease of configuration through a well-designed Airport Configuration Utility, and on-going firmware updates, even for the 9-year old one (!). For a variety of reasons, over time I ended up owning three of them – 2nd, 4th, and 5th gen, extending WiFi around the house (it’s a rental, so no CAT cabling).
In recent years, however, things have slowly but surely drifted toward sour. Airport Configuration Utility has been dumbed down a lot, and firmware stability seems to have taken a hit, too – I don’t remember ever needing to reboot a base station until a few years ago. The number of connected devices in the house has grown steadily – I consistently see around 10–15 connected at any given time. More and more neighbours’ access points popped up around. Usage patterns have also changed – kids have grown up, and now study and entertain themselves on various devices around the house.
So the connectivity grew spottier and less stable, and I couldn’t make things happy again no matter what I tried. Real-time online games kept stuttering, and chatting over the net kept breaking up. Not all the time, but often enough to be a nuisance. And in the backyard.. Well, there was no usable reception there, let’s leave it at that.
So enough was enough, and search for a replacement has begun.
