It Should Be Easy to Upgrade Your Load Balancer —And it Can Be

Applications have never been more important in business than they are today. And where there are applications, there’s a load balancer, working behind the scenes to ensure your applications can be used comfortably and safely at all times. When operating a load balancer, the most troublesome issue is upgrade work. Let’s examine the problems of traditional load balancer upgrades and take a look at VMware’s automated, streamlined solution: NSX Advanced Load Balancer.

Why do you need to upgrade your load balancer in the first place?

The main reasons to upgrade a load balancer are to patch vulnerabilities and bugs, to enable new features, and for EoSL support. A load balancer, located between users and applications, must above all be stable; we particularly want to avoid service disruptions due to defects in the load balancer software. For this reason, load balancer upgrades are inevitable. And for IT, the trick is to make them, as transparent and painless as possible..

For illustration, let’s take a look at a recent international case involving load balancers. To address software glitches, a project was running to upgrade hundreds of load balancers. The upgrade work was carried out little by little over several months, with operations personnel setting Continue reading

Risks and Rewards of the U.S. Broadband Funding Boom

The COVID-19 pandemic has taught us once and for all that broadband access is critical infrastructure. Without it, communities cannot work, learn, or earn online – a necessity during stay-at-home orders. And policymakers are taking notice. In the past few months, trillions of dollars have been proposed by the House, Senate, and White House for […]

Getting The Cloud But Keeping Control

The public cloud for years has tempted enterprises with the promise of much-needed agility and scalability that come with an elastic IT environment and of cost savings from not having to invest a lot of money upfront to buy a lot of infrastructure, adopting instead more flexible consumption models that allow organizations to pay only for what they use. …

Branch predictor: How many “if”s are too many? Including x86 and M1 benchmarks!

Some time ago I was looking at a hot section in our code and I saw this:

	if (debug) {
    	  log("...");
    }
    

This got me thinking. This code is in a performance critical loop and it looks like a waste - we never run with the "debug" flag enabled^[1]. Is it ok to have if clauses that will basically never be run? Surely, there must be some performance cost to that...

Just how bad is peppering the code with avoidable if statements?

Back in the days the general rule was: a fully predictable branch has close to zero CPU cost.

To what extent is this true? If one branch is fine, then how about ten? A hundred? A thousand? When does adding one more if statement become a bad idea?

At some point the negligible cost of simple branch instructions surely adds up to a significant amount. As another example, a colleague of mine found this snippet in our production code:

const char *getCountry(int cc) {
		if(cc == 1) return "A1";
        if(cc == 2) return "A2";
        if(cc == 3) return "O1";
        if(cc == 4) return "AD";
        if(cc == 5) return "AE";
        if(cc == 6) return "AF";
         Continue reading

Video: How to Dockerize a Python App with FastAPI

Join host Peter McKee and Python wizard Michael Kennedy for a warts-and-all demo of how to Dockerize a Python app using FastAPI, a popular Python framework. Kennedy is a developer and entrepreneur, and the founder and host of two successful Python podcasts — Talk Python To Me and Python Bytes. He’s also a Python Software Foundation Fellow.

With some skillful back-seat driving by McKee, Kennedy shows how to build a bare-bones web API — in this case one that allows you to ask questions and get answers about movies (director, release date, etc.) — by mashing together a movie service and FastAPI. Next, he shows how to put it into a Docker container, create an app and run it, finally sharing the image on GitHub.

If you’re looking for a scripted, flawless, pre-recorded demo, this is not the one for you! McKee and Kennedy iterate and troubleshoot their way through the process — which makes this a great place to start if you’re new to Dockerizing Python apps. Install scripts, libraries, automation, security, best practices, and a pinch of Python zen — it’s all here. (Duration 1 hour, 10 mins.)
