stackconf wrap up – DAY 2

We are back for day 2 and ready as ever. Everyone definitely felt a lot more relaxed and from the get go people were communicating with each other. We were welcomed back by Bernd and Christian and without wasting any time we jumped right into the first talk with Frank Karlitschek. Frank talked to us about “First hand experience: How Nextcloud stayed productive during COVID-19”. A very relateable topic for a lot of us that have spent a lot of time in home office and have had to change our way of working. Flexibility, communication and trust with remote work were key points and how we should act with our employees due to the change in environment. He also showed us some of the cool features that Nextcloud has to offer.

The great Migration

Nadja following Paul’s talk.

Paul Puschmann from REWE Digital was next to the stand and talked to us about “How we finally migrated an eCommerce-Platform to GCP”. Paul explained what was needed to transition their Platform to a Google Cloud Platform and how he managed to do it. He showed us the uses of Consul and the possibility of sharing it across more virtual machines and its functionality within Docker containers. There was a lot of discussion in the stackconf and there were a lot of great questions that Paul managed to answer both in his talk and on the channel.

“Monitoring Microservices The Right Way” was the next talk for today, which was presented by Dotan Horovits. Dotan talked to us about how the shift to microservices came with it’s difficulties with the introduction of Docker and Kubernetes. Dotan went over flexible querying over high cardinatlity and the requirments needed to monitor microservices efficiently with scalability to handle large volumes of metrics.

We took a short break with talks about Icinga and board games and UNO rules (you know what I mean). Back to the talks, Rodolpho Cocurde talked about his topic “Fuzzing: Finding Your Own Bugs and 0days!” Rodolpho is a penetration tester and is also an author in several magazines like Hakin9 and Pentest Magazine. He talked to us about the ever important issue on security and the different types of attacks, targets and an interesting fuzzing script in Python. He also demonstrated a great demo of how you can infiltrate malicious code with a buffer overflow through an mp3.

Developer on-call 24/7

Hello! Me at Tom’s talk.

Our next speaker Tom Granot spoke about his talk “On-call done right: how even a developer can help”. He showed us the Oasis Stack and how one develeper is on-call in order to stay active 24/7. Tom went on to talk about the wealth of tools available to developers to use in order to decipher problems that may arise in an area they are unfamiliar with. Not only that but also the things these tools don’t tell you and being able to “read between the lines”. Tom then demoed how to debug and check through services and transaction resources to find the cause of the problem when on-call.

During the lunch break Christian showed us the setup for Openstack and how everything is produced, which was a really nice insight as to what is going on in the background.

“Stretching the Service Mesh Beyond the Clouds” was the first talk after the break shown by Rosemary Wang. She demonstrated the uses of a service mesh, it’s advantages and disadvantages and the extra benefits of “streching” the mesh. Rosemary showed a typical topological map of how the services can be configured and the use of Consul and Terraform. The service mesh was then split over both a datacentre and a cloud which is great as it offers one place to control retries and error handling and progressive delivery across all environments. We saw a successful canary deployment and a manual reduction and redirection of traffic.

We all scream for icecream! 😛

Serhat Can joined us next to talk about “How DevOps changed the way we operate software”. Serhat spoke about the way software teams work together and the need for a shared responsibility. It is easy to push the blame onto another team, but what is needed is leadership support, transparency and ownership. He then compared software teams to formular one teams in a great analogy, where the expection should not just lie in one area, but the teams should be able to interact and take part in a variety of different departments.

How Agile are you?

Flo spotting Martin.

The next interesting topic came from Martin Hinshelwood with “The Tyranny of Taylorism and how to spot Agile BS”. Martin started off with some figures on what companies say they do and what they actually do. He then gave a quick recap of the management and work practices through the years and how they hold up today. Martin then engaged the audience with a series of truth questions that asked us whether or not our own companies are following the Agile guidelines, very creative!

After a quick break and discussions about board games and anime, we were joined by Lakmal Warusawithana who talked about “Reference Architecture for a Cloud Native Digital Enterprise”. Lakmal discusses the structure and operation on cloud native and the way the different tools are integrated. He tells us about how an API-led integration platform creates effective architechture and helps expand management capabilities. These capabilities help increase flexibility and productivity within a team.

Stephane’s Story: GitOps, Users, Drift

Our penultimate speaker for the day is Stephane Jourdan and “Why you should take care of infrastructure drift”. Stephane introduced IaC (Infrastructure as Code) users, their causes, consequences and also solutions and understanding drift. He then showed us a demo of how using driftctl can easily identify a problem with admin access and security groups from real world problems he had encountered. Driftctl could really save you from an embarresing talk with your manager!

Monitor everything with Thola

Last but definitly not least we had Tobias Berdin and “Introducing Thola – A tool for Monitoring and Provisioning Network Devices”. Tobias demonstrated the problems in monitoring by sending generic requests when specific requests are needed. This is where Thola comes in. It is compactly integrated into Ansible and serves as a unified interface for communication for a variety of devices with the added opportunity of creating additional device types.

Games, yeay!

The atmosphere from todays event was really great and one of my favourite things of the day was the amount of communication. Everyone really loosened up and got into the conference feel by chatting and joining our digital stackconf on Work Adventure. After the event there was a chance to relax and play some video games with everyone to help with the lack of seeing each other in person. Stay tuned for the final day and keep in the loop on our Twitter @NetwaysEvents.

stackconf wrap up – DAY 1

stackconf is back and better than ever! Today started off very strong with a few new additions and great speakers that gave us an insight to a variety of topics.

This being my first year at the conference, it was very exciting to get to started and involved with all the action and flow of all of the people coming together to learn something new. Right from the get go, you can see the amount of work that the Events Team put into making stackconf happen and the fact that it is all done online is really quite impressive. Of course we had the event online last year, but you can really see that this year has really been refined and delivered to a very high quality.

We’ve had a stackconf cake!

Before the conference had even started, people had already started communicating in the channel and this year they also had the opportunity to be “present” at the event. This year we made our own conference in the form of Work Adventure! This gave people the chance to walk around with their character and interact with people as if they were really there! This gave everyone the chance to be able to „meet“ with other people at the conference and have their very own chats with one another. The ones that didn‘t want to talk right away were busy sprinting around the conference area (me being one of them…).

We had a great kick-off from Bernd and Christian, who were both looking very smart and ready to guide us through the first day of stackconf!

Spot the Antipattern and the IKEA effect

Jumping into the first talk of the day Arushi Jain from Reddit kicked things off with her topic on Spot the Antipattern. Arushi showed us how to spot an Antipattern, why they exist and what we can do to help identify and avoid such patterns. This was also a very honest topic as Arushi went through some of the problems Reddit faced themselves and the systems they were using. She also talked about the use of certain methods and how sometimes they can be falsely used in lots of other applications instead of the ones they are meant for. An interesting point I picked up was the IKEA effect, where people that have made something themselves they have a hard time letting go and this was a very good comparison to code and current workplaces practices.

Katja tweeting.

Looking into our second talk, we’re greeted by Ara Pulido as she showed us Policy as code in Kubernetes with OPA and Kubernetes. This was another interesting topic and for those of you who are up to date with K8s, you would have found this talk very informative. Ara showed how some policy rules can be implemented to Gatekeeper so that pods can only be launched once they have reached a specific set of criteria. This can help avoid a wrong deployment and keep everything organised and working together. We got a quick look at the OPA Ecosystem, some constraint templates and a short demo on auditing pods to check to see if they are performing as planned.

We were gracefully transitioned through the talks by Bernd and Christian, who kept us chatting and talking in the channels whilst keeping the pace with all of the talks that went on today. Great job lads!

From Peter Elmer’s talk.

Our next speaker Peter Elmer came by with a very interesting topic about Data Driven Security. This gave us an insight into machine learning and how they incorporate data to make their programs „smarter“. Peter went into more detail as to how logic is created from data and turning decisions from a probabilistic factor to a more determining one. He also looked at how we can prevent attacking by defending at the source. This is a hot topic at the moment and also one to watch for the future.

Pragmatic application migration

Our next topic came from Nicolas Fränkel and he talked about Pragmatic application migration to the cloud with Quarkus, Kotlin, Hazelcast and GraalVM. Nicolas gave us some points as to why using the cloud is such a great idea and the benefits of doing so. He then went onto explain the different methods used when transitioning to the cloud and the drawbacks of having to rewrite everything from scratch. Alternatively, the use of JVM although it has a slow start up time, can be run once everywhere and adapts to the current workload. At the end Nicolas gave us a quick demo on a URL shortener, very cool!

Yummmm: stackconf and icescream!

To help break up the pace after lunch, we had two Ignites which were quick snippets of two very interesting presentations from Lawrence Finn and Tadeh Hakopian.

Lawrence talked to us about a cloud-sidecar application which sits next to your application and speaks to cloud services for you. The application even thinks it‘s talking directly to the cloud services!

More training methods are always better

Tadeh Hakopian then came by and talked to us about the importance of visuals when teaching code and reducing bias. Tadeh helps explain that removing barriers and using visuals helps make the first steps of developing easier and less scary when starting out. We have all been there before and looked at code thinking that it is something from The Matrix. Another good point he mentioned was that more training methods are always better, which is true as not everybody learns the same and this opens up a lot of opportunity for people that think differently. These methods help people build better room designs for example or build buildings more efficiently.

From Ricardo Castro’s talk.

Getting back on track with our talks, Ricardo Castro enlightened us with GitOps: yea or nay? Ricardo showed the advantages of using GitOps like enhanced productivity, stability and reliability.

He also went into the usefulness of rollback with applications as it is on the same basis of git we are all used to. The idea is to have a lot of it automated and out of the box integration. We then got the chance to see it in action with a demo of flux deploying an application and showing us how it pulls the information needed to work.

The scaler is very clever

Sebastian, Head of NWS, at stackconf.

Our next talk came from Bram Vogelaar and his topic on Autoscaling with HashiCorp Nomad. Bram gave us a brief look at how scaling was done in the past and how it has proceeded up until now. The great thing with Nomad is that is follows a very simple procedure, Keep It Simple Stupid. He showed us how easily the code is written and how the autoscaler works based on checks. The scaler is very clever as it is able to swell in order to keep up with demand, so you never run out of resources, and reduce them again so they aren’t being wasted.

Diego Ciangottini was up next to talk about Setup and Open Policy Agent for a multi purpose scientific platform. Diego brought up the demand for computing resources for the INFN communities, that are based all over Italy and their need to be able to obtain these resources. This very interesting and complex project looks at various computing challenges for data storage for multiple communities and the sustainable reuse of data. He then gave us a quick look at the solutions and user management with MINIO.

Our stackconf organizers Markus and Lukas.

Our next speaker was Matt Jarvis with a talk about the importance of Continuous Security – integrating security into your pipelines. Matt explained how the line between the roles of developers and security is increasingly getting blurred and how there is a need to bring the security checks to a developers level and the tools needed to do so. Of course this means a greater responsibility, which is why Snyk is there to help the Devs when checking their Pipelines a whole lot easier. Matt also went over some current flaws with current images and containers and then showed us how they could be checked and corrected by Snyk. Another great topic from our speakers.

We accidentally created a cloud

Great job, moderators!

Our last awesome speaker of the day was JJ Asghar and his very interesting topic, We accidentally created a Cloud on our IBM Cloud. JJ starts off with how everything started with ‘for loops’ on bash and the problems they faced and how they moved on to learning and using python scripts instead. Now as things have improved JJ explained the use of AWX and using Ansible playbooks to help run the code for you. With the help of their kubeadmin IBM are able to control a multitude of clusters all at once.

Although people may have been a little shy on the first day, which is understandable, the general atmosphere and communication from everyone was fantastic. We had a strong start to stackconf and we have a great feeling for more on what is to come. Our guests and speakers will have plenty of opportunities to mingle with other tech-heads and ask plenty of questions in the coming days. Keep up to date with everything that is going on and come and join the fun, it‘s free!

NETWAYS stellt sich vor – Andrew Constant

This entry is part 4 of 62 in the series NETWAYS stellt sich vor

Name: Andrew Constant

Alter: 30

Position bei NETWAYS: Junior Systems Engineer




Wie bist Du zu NETWAYS gekommen?

Vor meiner Zeit bei NETWAYS habe ich bei LIDL in England als Assistent des Filialleiters gearbeitet. Ich habe 7 Jahren lang dort gearbeitet aber etwas hatte mir gefehlt, ich wollte nicht für immer dort bleiben. Dann bin ich nach Deutschland umgezogen und habe mein neues Leben angefangen. Nachdem ich meine Ausbildung als Fremdsprachenkorrespondent abgeschlossen habe, wollte ich mehr in die Richtung IT gehen. Zum Glück habe ich NETWAYS entdeckt und war von Anfang an sehr Überrascht: Niemals habe ich bei einer Firma mit so einem coolen Arbeitsklima gearbeitet und jetzt habe ich das Gefühl, dass ich meine neue Familie gefunden habe.

Was macht Dir an Deiner Arbeit am meisten Spaß?

Immer mehr zu lernen. Jeden Tag ist anders und kann niemals mit einem anderen verglichen werden. Nicht nur die Aufgabe sondern mit wem ich arbeite und jedes Mal wenn ich ein Problem habe, gibt es eine Handvoll Leute, die darauf warten zu helfen. Ich freue mich auf die Zeit, wenn ich in ihren Schuhen stecke und den neuen Auszubildenden Hilfe anbieten kann

Was machst Du, wenn Du mal nicht bei NETWAYS bist?

Ich mag es zu fotografieren und die Fotos zu bearbeiten und suche immer das nächste tolle Bild. Fitness ist auch bei mir wichtig und natürlich finde ich auch andere Sprachen recht interessant.

Wie geht es in Zukunft bei Dir weiter?

Da ich schon seit 4 Jahren in Deutschland bin, möchte ich gern die Sprache (endlich) beherrschen und auch meine IT-Kenntnisse erweitern. Je mehr ich lerne und verstehe, desto mehr kann ich zurückgeben!

Mattermost vs Rocket.Chat

Rocketchat vs Mattermost: Which one is right for you?

Communication inside the company is crucial for any business, whether you have 20 members of staff or 1000. Every business needs a way to get their message across and a platform to do so. Why should messaging services just be used for social means? The capabilities of an open-source chat platform brought into a business environment is a utility that everyone needs to consider. Two of these contenders that are in the spotlight today are Rocketchat and Mattermost.

Both are great open-source chat apps with a clean interface that isn’t cluttered and all of your groups neatly categorized so you can see exactly whats going on. They have taken simplicity, efficiency and productivity and rolled it all into a package that can really propel the level of communication in your business. Think of the success of Whatsapp and Messenger and how they both deliver on a social platform, now apply that to a business environment where you can expand the possibilities of communication to greater heights.

Lets jump right into Rocketchat and what see they have to offer.

Right from the get-go you find yourself with a comfortable user interface that doesn’t jump out at you, but instead has been carefully laid-out to keep all of your chats and groups organized without having to trawl through 100s of contacts. The ability to manage groups and contacts gives you full control over what you see on your homepage neatly separated into categories of whats important to you. Being available for desktop and mobile devices you can take your chats everywhere with you and always be in the loop. Not only that but admin may also grant permissions to different users giving you control over how your chat operates.

Due to current circumstances more and more people are now doing home-office and Rocketchat is well equipped to make sure that business flows uninterrupted and could even be the bridge to new working opportunities. With audio/video conferencing, screen sharing and live translation in nearly 40 languages

already integrated, it will almost feel like your employees never left the office. As well as with email you also have the option to sign in from 3rd party apps like Facebook, Google and even Github. There’s no need to bring everyone into a meeting especially when some have to travel great distances or some are not currently in the office, just setup your meeting through Rocketchat and give everyone the ability to join from wherever they are.

For those of you concerned about privacy, you also have the option to self-host your chat, especially if you are interacting with your customers. You can have thousands of people in designated chatrooms which you have control over and you also don’t have to pay per person which could save you a lot of money! All of your data stays safe so none of your information will be passed onto a 3rd party.

  • Clean user-friendly interface
  • Control over permissions
  • Audio/video conferencing and screen share
  • Privacy is key, nothing is forwarded

Now lets take a look at what Mattermost has to offer and for those of you coming from Slack, you will have an easy time transitioning. Much like Rocketchat, you will see how nicely laid-out all of your menus are and you even have the opportunity to separate your groups further so each department can have their own channel for private or group chatting. You can also import your data from Slack directly so you will be away in no time.

Mattermost takes privacy to the next step with self-hosted deployment on premise or even to private or public clouds. Take control of your data and even after you decide to cancel, all of your information stays with you. Everything about you like IP addresses, usage patterns and even the details in your messages are kept secret so you don’t have to worry about them being passed onto anyone. There is also the optiono of Data loss prevention and complete operational auditability which grants you full access to logs of all server records, infrastructure/database changes and user activity.

One thing I love most about Mattermost is the customization of over 700 UI und UX apps and tools that can be integrated. You have an entire catalog of extensions, webhooks and even chatbots that can be implemented into the program to boost productivity and avoid consistent switching of apps and programs. Why have email, video call and screen share in 3 different programs, when you integrate everything into one and use it as a hub for all of your communication needs. Here you have the freedom to customize everything to how you want it to look and even create your own plugins.

Gone are the days of sending an email and waiting for a reply and having to cc everyone into the message. Here you can live chat with anyone in any group and even @ mention people where they will be notified either in app or when they are offline by email. Not only that but with silk smooth features like drag and drop file sharing, project management and custom emojis, your contacts will have no problem presenting projects and showing off their latest ideas.

  • Privacy+ keep all of your data even after cancellation
  • Integration from over 700 apps and tools
  • Smooth features for sharing and messaging
  • Endless customization possibilities

The great thing with both of these apps is it doesn’t just end there. Both being open-source opens the doors to unlimited possibilities in order to meet your needs. Make it your own and customize it however you like, don’t just be happy with the default you are given. And don’t just think of them as business only apps, they are perfectly suitable for private use especially now more people are spending time at home, possibly away from family, this is a great way to stay connected.

With plans to suit all of your needs Netways offers various packages that can be deployed instantly and ready to use within minutes. Whether you choose to host it yourself or publicly over the cloud, a more secure communication service with endless customization options is here and it’s working wonders.
