Vodafone’s Cloud Native Journey with Tom Kivlin

Vodafone’s Cloud Native Journey with Tom Kivlin

Some of the highlights include:


  • Why Vodafone moved to a cloud native architecture. As Tom explains, the company was struggling to manage operations across more than 20 markets. They also needed to improve the customer experience, and foster customer loyalty.
  • Why their business and engineering teams were both in favor of cloud native.
  • The benefits of deploying daily operational activities around a single cloud native platform.
  • An overview of where Vodavone currently is in their overall cloud native journey. Tom also explains how cloud native conversations have changed inside of the company throughout their journey, as various business units have caught on to the benefits of the cloud.
  • Vodafaone’s transition from outsourcing roughly 97 percent of their operations, to bringing 95 percent in house. Tom explains how this has improved efficiency and expedited time to market.
  • The challenge that Vodafone faced in trying to apply legacy network security solutions to distributed and dynamic systems.
  • Tom’s thoughts on why Vodafone’s cloud native transition and modernization efforts have been crucial to their success over the last five years.

Announcer: Welcome to The Business of Cloud Native podcast, where we explore how end users talk and think about the transition to Kubernetes and cloud-native architectures.



Emily: Welcome to The Business of Cloud Native. I'm Emily Omier, your host, and today I am chatting with Tom Kivlin. Tom, thank you so much for joining us.



Tom: You're welcome. No problem.



Emily: Let's just start out with having you introduce yourself. What do you do? Where do you work, and what do you actually do during your workday?



Tom: Sure. So, I'm a principal cloud orchestration architect at Vodafone Group. I work in the UK. And my day job consists of providing guidance and strategy and architectural blueprints for cloud-native platforms within Vodafone. So, that's around providing guidance to the software domains that are looking to adopt cloud-native architectures and methodologies and also to the more traditional infrastructure domains to try and help them provide their services in a more cloud-native manner to those modern teams.



Emily: And what does that mean when you go into the office—or your home office, go into your dining room where your laptop is, I don't know—what do you actually do? What does an average day look like?



Tom: It can vary. So, depending on the activity at the time, it could be anything from preparing a global policy that needs to go through the senior technology leadership team, to preparing some extremely detailed requirements for selection process or creating some infrastructures code, or the code artifacts for the deployment of cloud-native services, whether that's in our lab, or to help our services teams within Vodafone.



Emily: Tell me a little bit more about what pain made Vodafone think about moving to cloud-native and Kubernetes.



Tom: Primarily, it was the challenge of having 25 different markets, or 23 now. We launched a digital strategy to—so back in 2015, we launched a five-year strategy, which we wanted to massively increase the rollout of 4G, of converged network offerings, of improved customer experience. And we found that the traditional way of managing software was not supportive enough in our ambition. And so, having to choose cloud-native technologies, things like Kubernetes, but also the modern operating models, that was the driver: it was to improve our customer experience, and our customer-affecting KPIs, really.



Emily: And when you say it wasn't supportive enough, what do you mean specifically?



Tom: So, things like time to market, for example. So, if we wanted to offer a new service—so one of the things that 4G started the drive towards was a more granulated service offering to consumers, and so lots of different things could be offered. And if it took you six months to think of an idea and then have to go through—or even longer than six months to get to the point where that could be offered to customers, even if it was just a very minor feature within an existing product, then that's not going to engender customer loyalty. And so, things like the cloud-native mindset, where there's a much closer link between the engineering teams and the customer, there are much shorter periods of time between ideas coming in from the customers and then being delivered back to the customers as product features, that sort of time to market was really enabled by cloud-native technologies and mindsets.



Emily: And how does having two dozen, more or less, different markets, how does that play into the decision A) to move to cloud-native in general, and managing the IT infrastructure?



Tom: So, one of the things that's really driven it is trying to simplify and reuse artifacts. So, if you've got 23 markets all doing a different thing, then there's obviously a lot of duplication happening across the group, whereas if everyone's using the same technology in the same platforms—take Kubernetes as the example—everyone can write their software for that platform. Everyone can write their operational ecosystem around that platform. So, the deployment artifacts, the pipelines, the day two operational activities, they can all be based around that single cloud-native platform. And so, that enables a huge amount of efficiency from the operational side. And that in turn allows those engineering teams to focus on things that are adding value to the business and the customer instead of having to focus on fairly low-level tasks that are just keeping the lights on, if you like.



Emily: What's different for each one of those markets?



Tom: So, it might be something like language, it might be something as simple as that. It may be that the offerings are slightly tweaked. So, rather than, I don't know, as an example, rather than Spotify being included as a kind of add on, it might be some other service that's more relevant to that market. It may be that there are particular regulatory requirements that are specific to a market that needs to be considered within the product design and the engineering of it. And so, having a cloud-native response allows sharing and reuse of artifacts where we can, but still allows for that customization where it's required.



Emily: Where would you say Vodafone is in the cloud-native journey? Do you feel like you've, mission accomplished?

David and Goliath in the CMS Market with Thomas Schedler

David and Goliath in the CMS Market with Thomas Schedler

This week on The Business of Open Source, I spoke with Thomas Schedler, co-founder and CEO of Sulu. Sulu is a small, bootstrapped company that spun out of an agency; Thomas was recommended by someone to me as a guest, but when I first reached out to him he was skeptical about coming on the show because he wasn’t sure he was a good fit. But there’s a bunch to learn from this episode! Spinning out from an agency —> in my experience, one of the most common ways for open source companies to be bootstrapped, or even to be go on to raise venture capital, is to start out as a web development agency that uses a lot of open source tools.They are working on moving away from services and getting more revenue from the product; and Thomas talked about the advantages that they get from providing both services and developing a product-based business strategy.The CMS market is crowded! And everyone is open source, so being an open source company doesn’t differentiate the product at all. So how does Sulu differentiate itself in the market? Thomas talked about it. I loved that Thomas talked about how important opinions and technology choices are in differentiating themselves on the market. I also loved that Thomas talked about keeping some things out of the product as a way to differentiate themselves from others. Sometimes more features can deliver less value to users. How being small can allow you to move quicker, and that gives Sulu and advantage over the huge players in the CMS market.Why differentiation and knowing your niche is so important when you’re a small company competing again large players. Do you need to differentiate yourself in a crowded market? You might want to work with me.

Open Source Firmware for EV Charging Stations with Marco Möller

Open Source Firmware for EV Charging Stations with Marco Möller

This week on The Business of Open Source I spoke with Marco Möller, CEO and co-founder of Pionix. This was a fabulous conversation about a company that’s in a very different market from the usual open source company: They make firmware for EV charging stations, and are behind the EVerest project, which is part of LF Energy. So who is part of the community open source projects that are so connected to hardware? Here’s what we talked about. There aren’t many hobbyists in the community — but there are a lot of people who have professional interests in the electric vehicle industry. EVerest doesn’t focus on what Marco considers “personal” or “hobbiest” features. This was a great discussion about how understanding the target market, including for the project, leads to different feature decisions. How does Pionix money? It doesn’t yet :), but we talked about various plans the company has for monetization in the future. How being involved with the LF Energy has helped build trust, which is very important for a company that is only going to be selling to large companies and governments. Why Marco thinks that the huge vision he has for creating firmware for EV charging stations is only possible with open source, and how he makes sure that he’s able to fund the large mission without hurting the community. The balancing act with getting investors who specialize in the energy market but who don’t have experience with open sourceStruggling with positioning your project or figuring out how to best monetize? You might want to work with me.

AI-generated Code Copied from Open Source with Julian Coccia

AI-generated Code Copied from Open Source with Julian Coccia

This week on The Business of Open Source, I spoke with Julian Coccia, CTO of ScanOSS, about selling access to data while making open source software. Of course, we also talked about being an open source company that is also deep in the open source world, helping companies understand their reliance on open source code and how open source is used in their codebase. Several things that we talked about: AI and open source code. This is a topic that’s slightly tangential to business, but very interesting to me. If you’re using an AI code generator, you are almost certainly putting verbatim copies of open source code into your codebase, but without realizing you’re doing so and without any understanding of the license requirements. This is a huge compliance risk. 2% of code generated by AI is a verbatim copy of open source code. How the biggest challenges isn’t necessarily monetizing, but getting visibility into the sales funnel. It can feel random and sudden; a company appears out of nowhere ready to sign a contract because they’ve been using the open source project for months. This is the last week to get tickets for Open Source Founders Summit, so if you want to join other leaders of open source companies May 19th and 20th in Paris, get your tickets now!

How to be Successful when Donating a Project to the CNCF with Liz Rice

How to be Successful when Donating a Project to the CNCF with Liz Rice

Today on The Business of Open Source I spoke with Liz Rice, Chief Open Source Officer at Isovalent, which is now part of Cisco. We addressed two subjects: How to be successful as a company that donates their project to the CNCF, and the story of Isovalent’s acquisition by Cisco and the role open source played in that acquisition. We talked about: Trademarks. This is a very important part of what you donate when you donate a project to the CNCF (or other foundations). We talked about what you can and can not do with the name and logo of “your” project when it becomes part of the CNCF, and what that means for the competitive landscape you’re a part of. How to best take advantage of the marketing benefits that being part of the CNCF brings. How to create a link between the CNCF project and the company that donated it. The role that Cilium and eBPF played in Isovalent’s acquisition by Cisco. Why Isovalent’s relationship with open source is valuable to Cisco in and of itself. How open source companies can increase the likelihood that they’ll be able to continue investing in open source post-acquisition. Why it’s so important to find opportunities for collaboration. Want help making the link between your CNCF project and your commercial product? You might want to work with me.

Open Source Manifestos with Vincent Untz

Open Source Manifestos with Vincent Untz

This week on The Business of Open Source I talked about Open Source Manifestos with Vincent Untz, CTO of Centreon. The entire conversation focused on this idea of open source manifestos, which Vincent is going to talk about at Open Source Founders Summit — and I had never heard of before. The idea to create an open source manifesto came about because internally there was a lot of frustration around Centreon’s relationship with open source. A lot of people, especially those who didn’t come from an engineering background, would routinely ask why the company invested so much in open source. At the same time, there was a feeling among the engineering team that the company’s commitment to open source — and the concrete development time spent on open source — was slipping. After creating the manifesto, the doubts about why open source mattered went away immediately — there hasn’t been a single conversation calling into question why open source matters since the manifesto was finished. Now conversations about open source are different. Externally, there’s been a huge change in conversations around open source. People say things like “Centreon is back in the game.” It’s hard to point to concrete financial results as a result of the manifesto, but there have been differences in relationships with partners for sure, and it has helped get more companies to contribute to the project. Want to see what the Centreon Open Source Manifesto looks like?

How a Rebrand Increased Sales with Lukas Gentele

How a Rebrand Increased Sales with Lukas Gentele

This week on The Business of Open Source, I spoke with Lukas Gentele, the CEO and co-founder of LoftLabs. Here’s some of the things we covered: There are many open source projects at LoftLabs. We talked about what the team did differently the second time round, when they’d had the experience of creating the first project under their belt, and why they continued creating additional projects after that. How they make roadmap decisions to decide what goes in the OSS versus what goes in the enterprise editionHow they thought about the benefits to the business from open sourcing vCluster, the second project they released, and whether or not the theory about how it would benefit the business ended up being correct. Whether or not open code is necessary for community building, and why. In particular, we talked about the difference in how people feel ‘ownership’ of open source projects when they contribute to them. The pros and cons of building different brands around your project, your product and your company; and of having different brands around your different projects. We talked about this a lot; LoftLabs has a different company brand from any of the products or projects, but they discovered that if the project and product do not have the same brand, people get so confused that they ultimately do not buy. If you need to figure out how to brand your project and product, you might want to work with me. If you want an opportunity to talk with other founders about branding, community building, and more, you should join us at Open Source Founders Summit May 19th and 20th in Paris.

Fundraising and M&A for Open Source Companies with Daniel Jarjoura

Fundraising and M&A for Open Source Companies with Daniel Jarjoura

This week on the Business of Open Source I spoke with Daniel Jarjoura, an investor at Avolta who specializes in developer-facing companies, and who writes a newsletter on developer-facing startups and also collects data on investments in open source companies. We spoke about the overall state of investment for open source companies and specifically the state of investment in open source companies in Europe. Here’s what we talked about: Differences between venture funding for OSS companies in Europe and in NAHow open source companies were relatively stable in terms of getting venture funding, even as the entire venture funding ecosystem was in free-fall.How it might be true that European investors don’t understand open source companies, but on the other hand plenty of North American investors invest in European companies. Do developers trust open core companies? We had a discussion about whether or not open source companies have a trust problem…How important communication is for open source companies, something that I think is very true — a lot of the problems that open source companies run into when they either adopt an open core model or even when they do a license change. How founders can do a better job communicating with their VCs, including how to do a better job targeting appropriate investors. What do optimizing for in the VC relationship … and spoiler alert, that is for money. You might want a perfect VC who can make introductions, give you advice, give you money, be nice, etc. But the most important thing is the cash; focus on that. The second most important is the introductions. But advice isn’t something you should count on from VCs, and that really isn’t a VCs job, anyway. We finished the conversation with a discussion about M&A for open source companies. If you want good advice about your open source company, you might want to work with me. If you want an opportunity to talk with other founders about things like M&A for open source companies, communicating with VCs, and other topics specific to open source companies, you should join us at Open Source Founders Summit May 19th and 20th in Paris.

Products, consulting, and open source with Andrew Martin

Products, consulting, and open source with Andrew Martin

This week on The Business of Open Source I spoke with Andrew Martin, CEO and founder of Control Plane. Control Plane is ultimately a consulting company, as Andrew introduced it. But the company also created and maintains KubeSec, and also has an enterprise version of Flux CD that it licenses. That gives this conversation a slightly different flavor from the usual. Here’s some of the things we talked about: The business ROI that Andrew expected to get from releasing KubeSec, and whether or not he as actually seen those expected results play outThe difference between bootstrapping a company by offering services and by offering consulting — specifically what the difference between services and consulting is. The problem with “drive-by” feature development in open source projects — when people contribute features but don’t commit to the ongoing maintenance of the projectWhy Control Plane decided to release an enterprise version of FluxCD, and how the enterprise version of Flux is differentiated from the pure open source project. Why underinvesting in marketing, especially in marketing for the open source projects, was a mistakeJoin us at Open Source Founders Summit if you want more conversations about how companies are built around open source projects, from consultancies to large corporations.
