海外TECH	The Apache Software Foundation Blog	Inside Infra: Chris Lambertus --Part II	https://blogs.apache.org/foundation/entry/inside-infra-chris-lambertus-part1	Inside Infra Chris Lambertus Part IIPart II of the of the quot Inside Infra quot interview with Chris Lambertus the last of the series of interviews with members of the ASF Infrastructure team who share their experiences with Sally Khudairi ASF VP Marketing amp Publicity quot you want to limit your exposure You have to keep that in mind as you move through the day to make sure that you are minimizing your risk and minimizing your security threat vectors quot catch up on Part I of the interview So in the scope of the team I understand that you re a more quot senior quot developer Not that you know better it s not an issue of better or worse but you re more seasoned How does ASF compare to other groups that you ve worked with Are there special technical requirements or special security issues you have to be concerned with Especially as we mentioned before it seems like there s an unlimited number of project development environments Are there certain things that you have to consider or accommodate or do that s so different with ASF that you ve never experienced before Can you give a little bit of a frame of reference for folks unfamiliar with how it is within the ASF First of all I m not a developer I am terrible at programming Absolutely I m awful at it I don t consider myself a developer in any way shape or form I am a system administrator Administrator Okay so you re a more quot senior quot sysadmin then I hesitate to use the word senior because it has some implications in the industry that I don t necessarily feel are appropriate for the ASF I believe that I have been doing it longer than most other people on the team just as a career I m guessing that s probably what you mean by that Right That s why I used the word quot seasoned quot also It s hard because some people go quot Are you saying I m old or are you saying hierarchical that I m above others quot It s a hard way of describing it because some folks have been programming or dealing with computers since there were kids others later in life but you guys are all moving in the same direction So how does one describe it Yeah I think seasoned is a good word Just like I said I ve been working in the industry as a system administrator since pretty much continuously with some brief changes in the s It s not here nor there So it s not hierarchical Everybody is equivalent in terms of the Infra team Nobody s above anybody else or below anybody else right I was wondering how is the ASF different from other groups you ve worked with All right It s actually not all that different There are a couple of things that make it unique Well a number of things that make it unique One is that it s completely remote and completely geographically dispersed Two is that the participants on the team are all from very different backgrounds and cultures and countries which is fairly unusual for a system admin team a small system admin team I would say But beyond that it actually shares quite a lot of things that I typically see in system administration teams There s a central job board if you will like the Jira stuff There s a communications channel We have Slack There s a nominal leader in Greg that directs the general movement of the barge Yeah by and large it s pretty similar with most environments that I ve worked in I mean some are much different Some are very corporate some are very open Yeah now I remember one of your previous questions one of the biggest challenges that I found is the openness The ASF for quite some time has been incredibly public with its configurations with its systems with its documentation These types of things are very unusual in the corporate world or in commercial IT Typically you would never make that stuff public The fact that it is and has been at the ASF that s been a challenge for me It s an unusual way to maintain systems It s got some downsides Having that stuff available can be concerning at times How so Help me understand this because I ve been with the ASF forever What you re mentioning right now reminds me of about years ago something failed in Infrastructure I can t remember what it was but it was a big thing People were talking about it It was even in the press at the time It wasn t catastrophic but it was big We actually wrote a blog post about it and we presented about it at ApacheCon From a marketing perspective and a media perspective I was uncomfortable because from a corporate perspective you don t do that The fact that we not only encouraged it but published it and educated everyone about it admitted it ate it all we took responsibility quot Here s what failed Here s what happened Here s what we did quot People found this to be extremely refreshing extremely helpful and it was totally eye opening for me I had no concept of anything like that before and I d been with the ASF for like years already I ve never seen us opening the kimono at that capacity So I m coming at it from a slightly different perspective as you I understand you don t want to have your config files public Obviously that can put you at a different level of exposure and risk Exactly Is that required or is that just part of our culture saying quot This is what we do quot It s definitely part of the culture My background is heavily in computer security Coming on board to the ASF and seeing all this stuff out in the open to me was I couldn t believe my eyes quot You re doing what quot So I ve actually worked quite a lot to reel that into some extent because even years ago was nothing like what s happening today in the world of computer security in the terms of the threats in terms of what people are looking for what people are doing and what people are capable of doing right Even to benevolent organizations like ASF it s distressing So one of the things that I ve really tried to encourage is it s okay to be open to some extent but you have to have some common sense about your security exposure That s what I ve been trying to do just for the entire time that I ve been here is just to try and reel some of that in without losing the culture because I think the culture is valuable Like you said the incident that happened whenever that was I think it was a right decision for the time Would you do that today Probably not It s not because you wanted to cover something up but it s because you want to limit your exposure Yeah so it s a different culture now not the ASF but the world in general You have to keep that in mind as you move through the day to make sure that you are minimizing your risk and minimizing your security threat vectors All right Have you had instances where a project has basically treated you as their dedicated resource Has anyone made unusual demands of the team I m not asking you to name names but I can imagine it can get out of hand with all these different projects especially the corporate ones Absolutely Yeah the corporate ones are typically the biggest problems because they come in with a much different mindset than somebody who s come in from developing an Open Source package and has brought it to the ASF The corporate projects that we ve seen really are the ones who are the purveyors of that mentality They feel Infra is their personal resource because they don t really have an understanding of the scope of the Foundation They don t have an understanding of the amount of projects that Infra supports So I don t really fault them for that because it s just a matter of education They just need to understand where they are placed in terms of the Foundation in terms of Infra s availability and scalability Once we ve explained that to people they get it We typically don t have any problems after that But there are a few projects that have come in and just persisted in wanting weird stuff Some of the things you can provide Some of the things you just got to kick back and say quot Hey this is not something quot Like I mentioned earlier if it doesn t have a broad benefit to the Foundation if it s something really specific to your project Infra is probably not going to support that for you because we can t support all these one offs So we ll say quot We ll give you a VM You can do it yourself quot That s worked out pretty well but there ve been a few cases even where people like Greg and David have had to go and talk to these projects and say quot Look how you re approaching this is not appropriate You need to pull it back You need to rein it in quot But that s really pretty uncommon I would say just a basic education as people come through the Incubator is sufficient to dispel most of that Those kinds of projects Do they stand down or they wind up hiring their own committers to do their Infra work Do you have any idea as to how that works I m seeing more projects coming in with more diversity in their committership to take care of marketing stuff for example That s expected especially as they scale but from the site administration side of things Website stuff it s a very interesting thing to observe Some project sites information is stagnant they re focused on specifically developing code Others are super productive in terms of getting stuff done I m always wondering how are they able to handle all this Curious to see if you had ideas as to what s going on there I will say this documentation is hard right Writing code is comparatively easy and it s a lot more fun So when you re developing a product your natural instinct is to develop the product not develop the documentation So you get a project that s only got a couple of active members They re probably not going to spend most of their time writing documentation They re going to spend most of their time trying to advance the code base Even within Infra that s been a huge challenge for us Now that we ve hired Andrew ASF Infra team member and technical writer Andrew Wetmore to help us work on some of this documentation it s becoming extremely clear as we work through it how much of that documentation has been untouched It s been stale for all the same reasons as these projects Yeah Some projects will say quot Hey we need a documentation guy That s what Infra said we need a documentation guy quot They ll find one Maybe somebody will volunteer or maybe it s a corporate thing whatever So yeah I think it really depends on the project Some people have the resources Some projects have the resources and some don t Yeah it s interesting Again since day one since the s documentation has always been an issue for all projects even when we started with just HTTPd It s a constant issue nbsp If I was going to have money to do anything in a project I would use it on documentation Documentation is often the thing we need the most I mean how is it going to work otherwise Yeah I agree Even from just a cognitive aspect writing code and writing documentation are about polar opposites The type of mind that goes and writes code isn t usually the type of mind that can write documentation or can write meaningful documentation I m guilty of it myself I can t write documentation I find it quite difficult Where building packages and tying things together and Puppet configuration management is not difficult for me So it s a huge mind split between those two types of things I absolutely agree that hiring somebody to do documentation is a great use of resources We ve grown a lot during the time you ve been with us now six plus years Other than scale how has Infra changed over the years What s unusual is that the team is getting smaller I would presume as the Foundation is scaling upwards you would have more team members It s some crazy number five people six people it s so small It s hard to understand how you guys handle everything Yes six people including Andrew and then Greg right Including Andrew that s six but Andrew doesn t handle the day to day Jira stuff anyway He doesn t handle tickets So you really are a tiny group From your perspective and your experience would you say that that s a small group considering the workload and the demand Yeah I would say so Probably based on my experience in other organizations about half the size that it would be in a commercial environment Well to go to your original question there in terms of what s changed I think prior to David Nalley I would say that Infra was extremely reactive I think that s changed quite a lot I think David has really brought an element of customer service and customer focus to the team that really had been somewhat lacking in the past So that was a proactive decision to go in and say quot We have to better serve our projects quot right Yeah I really do credit David with that I think he brought a huge amount of that to the team and that mindset It s really improved our relationships Infra s relationships with the projects It s helped us develop tooling like Self Service The more that we can move off into those projects do it yourself tooling the better off we are because it s less tickets that we have to handle It s a constant juggle for us between dealing with legacy code dealing with technical debt from years and years and years and years ago to doing modern things to bring out new tools and all the while supporting projects In what areas are you guys experiencing bursts of growth or demand Everyone has a slightly different perspective I know CI comes up a lot in this arena Greg s always saying since I deal with ASF s Sponsors quot We need more quot Where do you feel Infra s growing at the highest rate or the most interesting rate Where do you feel like that s happening Yeah continuous integration was the first thing that came to mind when you said that The more projects we have the more need there is for CI That s fairly linear Other growth places are things like Infra VMs machines that we run to support Infra services internally Prior to the resources that we have now we used to have a lot of monolithic systems systems that would run a lot of things Think of a machine like Minotaur which used to run two dozen services on one machine That s not a best practice at all Moving to aggressive use of configuration management Puppet and making sure that systems are easily replicable with the configuration management has allowed us to really build not quite micro services but single purpose systems which are a lot easier to maintain a lot easier to scale than some of those monolithic systems So that s been a big growth area for us Just the number of VMs number of systems that we re maintaining it s got to be in the hundreds at this point I haven t counted Yeah These microservices that you re mentioning also reduce the single point of failure which is critical That keeps you guys scalable and keeps you up and running That s important Yeah that s right I m curious when was the last time you guys had a fire drill type of thing where everyone s hands on You had something recently right A couple months ago all hands on deck there was something broken You guys were able to resolve it pretty quickly but that s uncommon where something breaks in its entirety I don t want to say anything about this because it s going to cause a problem We can go off the record What I mean is I m going to say it s fine right And then something s going to break laughing You don t want to jinx it Okay We have failures from time to time We ve had some situations where there s been a problem at a colo One of our VM providers had an issue and we lost machines We had to rebuild them with Puppet our configuration management and restore stuff from backup It sucked but it wasn t a disaster right Because we have the backups We have the capacity We have the configuration management So nobody had to wrack their brains “How did this work How did this go together We ve made very very big strides in avoiding that old mindset of one guy set this up years ago and nobody else knows how it works We re very much trying to avoid that these days Right bus factor Yeah yeah yeah The configuration management systems have been absolutely critical with that So that continues to grow We continue to add to configuration management wherever possible and just make sure that those systems are able to be reconstituted wherever whenever it s needed Cool cool Okay What do you think people would be surprised to know about ASF Infra The other guys probably said the same thing but probably the amount of stuff that we support from the number of people we have I think that would probably surprise most people in the industry That s one answer I think it was Infra team member Chris Thistlethwaite who said quot that we exist quot that you guys exist People don t know how it happens It s like magic I ve always talked about how Infra is this crazy magic impossible story It s like The Little Engine That Could because you guys are such a tiny group You have such a good working relationship and everyone is connected From the outside it seems like a completely seamless operation There s this magic thing behind the scenes and then you find it s only five six people running it That s mind blowing It s incredible I hope that people have that perception We do try to provide a unified front In reality there s not really any infighting in the team We all generally know what needs to be done We all generally agree on how to do it So the disagreements are fairly minor and not all that common Well that in itself is unusual right Think about it I mean there s a lot of factions and politics and weirdness but that tends to happen with larger groups So you guys make it work in a way that s awesome I think one of the things that makes that the way it is is because we re all supporting the ASF right We re all here because we support the Foundation and we want the Foundation to succeed So that drives I think a lot of the direction and the way that we approach how we support the Foundation You guys have a very different common goal right You re there for the benefit of the Foundation with a capital F Projects are there to work on their own thing Of course if they can help everybody else that s good too But the focus is different nbsp What is your favorite part of the job I have to say the flexibility and the remote aspect of it along with the constantly changing technology There are a lot of opportunities to learn new things and work on new technologies nbsp You are all on call for certain periods throughout the week right So because of your to are you ever on call overnight or does that just not work out with schedules or it doesn t matter Well we rotate on call So you re on call for a week at a time starting at I think or Pacific AM and then going through the following week So typically what happens is you ll get the pages when you re on call regardless of the time of day or night But the way that it works out typically because we have folks in Europe we have folks in the US we have folks on the West Coast and the East Coast that almost always there ll be somebody awake and available to answer Sometimes in the middle of the night if my pager goes off at in the morning I ll look at my phone and I ll see that Humbedooh or Gavin is already working on it Thanks guys Obviously the same is reciprocated right If the phone goes off in the middle of their night and I see that they re on call but it s in the morning I ll grab a ticket if I can I ll grab the call if I can We just try to help each other out that way You guys are a true team you have each other s backs in a way that again is unusual to see It s almost like family but even better because even family has infighting and issues You are there for each other which is really really cool to see Yeah let s say we ve had our disagreements but it is a very familial atmosphere When you first came into the role what was your biggest challenge Was it what you thought it was How was your experience It was an incredibly steep learning curve When I first started here we were in the middle of the transition from the quot one guy who set up everything a volunteer five years ago nobody knows how it works quot environment to a configuration management We were nbsp just starting to get into that and shore up some of our documentation at the time For me just coming in and learning all the different systems and all the different processes and all the different edge cases and one offs and locations for things and who s who and all these that was incredibly difficult It took me probably at least a couple of years before I felt comfortable with most of the systems Even today there s stuff out there where I ll be like quot I m not sure what this means Do you have any idea what s going on quot Because there s so many little pockets and holes and places and things and historical legacy stuff It s very complicated It s been organically grown over a long long time With a lot of different personalities and a lot of different processes that is what s unusual The quot quilt quot that makes Apache is so diverse It is What are you most proud of with your career with Infra so far I m not really sure to be honest I don t tend to think of things like that I can t really single out one thing and say quot Hey I m really particularly proud of that quot or whatever I try and take pride with all my work Building better backup systems I think is definitely a big one Just getting through some of this mail project has been good as well When I finally got everything working that was a pretty proud moment there I felt pretty good about that That was a complicated system It s still a complicated system I m still not sure it all works right That s why we have to test it By and large I m feeling pretty good about it That s great How would your coworkers describe you laughs Grumpy laughs The response is the same with everyone Everyone laughs but grumpy is the first one I ve ever heard I don t really talk too much I m not a super verbal person So I always seem to come across as grumpy on the chat systems there It s a schtick I guess but it is fun I m not really grumpy Well most of the time What are the biggest threats or concerns that sysadmins need to watch out for I don t mean doom and gloom unless there s actually doom and gloom A lot of non Apache folks are curious what the Apache guys think So is there anything that you could share in terms of advice or trends that are coming up or something that people should be aware of moving forward Security backups disaster recovery those are the keystones of any organization that you absolutely must have in place to sleep at night If you don t have any one of those three you re in grave danger of doom and gloom That makes sense What is your greatest piece of advice for someone looking to have a job like yours Oh boy Run for the hills laughing Work with as many different things as you can learn as many different things as you can and try not to get stuck doing one specific thing I think in my career I ve been such a jack of all trades that it s really helped me to be able to see and build systems that work with a lot of different technologies You get some people coming in they re IBM guys like a specific subset of IBM AIX expertise or something right That s all they do And then when the situation comes around well nobody s really using that anymore you run into a problem because you re not really marketable anymore So the advice that I would give anybody who s trying to get into the system administration field be broad and learn as much as you can about as many different things as you can If you had a magic wand what would you see happen with ASF Infra I think I d probably just give us more resources I mean I don t really have any complaints to be honest I think if we had more then we would do more More machines or more cash or more team or more what All of those I think more cash Being able to buy more physical compute resources would go a long way for us We do rely so much on donations and donated resources that it can be a little bit daunting when that donation goes away and you have to scramble to fill the void Staffing is a complicated one because it is familial Having somebody new come on board it s challenging It s nice to have an additional person be able to work on stuff but going through the process of integrating them into the team and teaching everything else it s daunting it s challenging So I think having more resources would be more important at least to me than having more staff because I think we re doing all right with the staff that we have now So that s just my perspective Chris is based in California on UTC
