I woke up last Tuesday (March 12, 2019) to find an interesting announcement in my inbox. NGINX, the software networking company, well known for its NGINX web server/load balancer, was being acquired by f5. f5 is best known for its network appliances which implement network security, load balancing, etc. in data centers.
The deal was described as creating a way to “bridge NetOps to DevOps.” That’s a good way to characterize the value of this acquisition. Networking have begun to evolve, or perhaps devolve, from the data center into the container cluster. Network services that used to be the domain of centralized network devices, especially appliances, may be found in small footprint software that runs in containers, often in a Kubernetes pod. It’s not that centralized network resources don’t have a place – you wouldn’t be able to manage the infrastructure that container clusters run on without them. Instead, both network appliances and containerized network resources, such as a service mesh, will be present in microservices architectures. By combining both types of network capabilities, f5 will be able to sell a spectrum of network appliances and software tailored toward different types of architectures. This includes the emerging microservices architectures that are quickly becoming mainstream. With NGINX, f5 will be well positioned to meet the network needs of today and of the future.
The one odd thing about this acquisition is that f5 already has an inhouse project, Aspen Mesh, to commercialize very similar software. Aspen Mesh sells an Istio/Envoy distribution that extends the base features of the open source software. There is considerable overlap between Aspen Mesh and NGINX, at least in terms of capabilities. Both provide software to enable a service mesh and provide services to virtual networks. This raises the question “Why buy NGINX if f5 already has Aspen Mesh?” Sure, NGINX has market share (and brain share) but $670M is a lot of money when you already have something in hand.
NGINX and f5 say that they see the products as complimentary and will allow f5 to build a continuum of offerings for different needs and scale. In this regard, I would agree with them. Aspen Mesh and NGINX are addressing the same problems but in different ways. By combining NGINX with the Aspen Mesh, f5 can cover more of the market.
Given the vendor support of Istio/Envoy in the market, it’s hard to imagine f5 just dropping Aspen Mesh. At present, f5 plans to operate NGINX separately but that doesn’t mean they won’t combine NGINX with Aspen Mesh in the future. Some form of coexistence is necessary for f5 to leverage all the investments in both brands.
The open source governance question may be a problem. There is nervousness within the NGINX community about it’s future. NGINX is based on its own open source project, one not controlled by any other vendors. The worry is that the NGINX community run into the same issues that the Java and MySQL communities did after they were acquired by Oracle which included changes to licensing and issues over what constituted the open source software versus the enterprise, hence proprietary software. f5 will have to reassure the NGINX community or risk a fork of the project or, worse, the community jumping ship to other projects. For Oracle, that led to MariaDB and a new rival to MySQL.
NGINX will give f5 both opportunity and technology to address emerging architectures that their current product lines will not. Aspen Mesh will still need time to grow before it can grab the brain share and revenue that NGINX already has. For a mainstream networking company like f5, this acquisition gets them into the game more quickly, generates revenue immediately, and does so in a manner that is closer to their norm. This makes a lot of sense.
Now that the first acquisition has happened, the big question will be “who is the next sellers and the next buyers?” I would predict that we will see more deals like this one. We will have to wait and see.
One of the reasons I have been so quiet lately is that I have been simultaneously writing two papers and causing trouble. In the first case, my single paper on service mesh technology and its market turned into two papers: a technical guide and a market guide. The original paper was much too long. Let’s be honest, none of us have the attention span to read through 16 pages of dense technical and market insights. We’d rather have two papers. The first paper, a primer on service mesh, will be released at the beginning of April and the market guide at the beginning of May.
Now, to the “causing trouble” part. I recently wrote an article for CMSWire about bias in IT. Sorry but we all know that sexism, racism, and ageism are running rampant in the IT field. I decided to look up some stats on anti-diversity bias from Data.com, which packages and publishes government data (in other words data you can trust as not made up) and found myself pretty angry about it.
Seriously, it’s embarrassing for an industry that prides itself as a meritocracy. If you are you are a young, white, male, you are not just advantaged, you are hugely advantaged. You can read the article at CMSWire. It’s easy to blame the victim and look for reasons different groups are underrepresented and underpaid. It’s equally easy to look for exceptions to the rule as proof that the main effect doesn’t exist. That doesn’t stand up when the trend plays out across all demographics. The best explanation is a culture that either drives away or outright discriminates against anyone not young, male, and white.
So, watch for those papers and go do something about the problems of bias. Two good ways to become awesome.
