Transformation and building CCoE teams in the largest banks in Poland

The first thing that had to be done to introduce the public cloud to the largest and most regulated bank in Poland was to remove from the bank's regulations that the public cloud is dangerous and completely prohibited.

But the hardest thing was finding the „Rascal Engineers” who wanted to do it and pushing far away all those who disturb them. If you want to listen to how to build organizations as part of the road2cloud transformation and hear what worked, what to avoid and what are the tradeoffs, I cordially invite you to my speech at the most interesting cloud conference.

See you soon „Rascal Engineers”!

Przemysław Malak

Aggregation of events on the example of one of the largest financial institutions in the world

Using the public cloud means living with events. Utilizing more than a thousand AWS accounts means living with many events.
Decoupled, asynchronous applications and event-driven architectures can produce and consume countless events propagated between accounts and regions.
Besides that, we have the cloud environment, which produces hundreds of additional events we want to take care of. Services like GuardDuty or IAM Access Analyzer can be very "loud".
I will show how to leverage Amazon EventBridge and other cloud-native services to make our life easier.

What is the future of the Data Center?

The acquisition of UPC in Poland by Play means the creation of a new tycoon of convergent services - a combination of the largest mobile network operator in the country with UPC's fiber-optic internet and TV offer.

Why should this information interest the participants of one of the oldest cloud computing conferences?

We must not forget that from 2019, 3S Data Center - the owner of 7 data centers and a provider of complete cloud solutions, is an important part of this business.

The topics that our speakers will cover include

  • process of merging these entities
  • how to build solutions based on own products and public clouds for the entire B2B market
  • 3S Data Center development plans in view of the growing popularity of the public cloud,
  • investment in technology partnerships with suppliers such as Veeam

Cybersecurity challenges in a modern multi cloud based environments

Security challenges evolve in line with IT platforms. We paid attention to completely different aspects of cybersecurity in the context of on-premises environments, different for private/public cloud environments, and today we face challenges related to modern hybrid / multi cloud environments. What are the key security aspects we have to cover when dealing with multi cloud platforms?
During the presentation, we will go through the key risk factors affecting the security of multi-cloud environments and talk about the practical side of their mitigation.

11:45 - 12:15

Wojciech Barczyński

Adding policies to your Golang App with Open Policy Agent

It might feel like chasing a rabbit to keep up with users’ requests for new configurations and policies. It is even more challenging if you build for power users. In the talk, I will show how to use the Open Policy Agent (OPA) for these scenarios, share our experience in Spacelift, and present how to integrate OPA into your Golang application.

How to build a Bank in a year on GCP? History of VODENO and AION Bank

Over 4 years ago we started the Vodeno project. 3 years ago, our banking platform was launched in the GCP public cloud for the Friends & Family phase. In November 2019, we successfully completed the complete migration of the Belgian bank (Aion) to our cloud. We have already talked about "how to build a bank in the cloud" many times. Almost 3 years have passed since then. The platform has expanded and 4 countries are already operating (Belgium, Poland, Germany and Sweden). During these 3 years, the company's strategy changed and the application layer also changed. In retrospect, we know that apart from these good architectural decisions, there were also those that were wrong (theoretically good at a given moment in time) - for example: separate environments for each country. We are currently running a project called Multibranding, i.e. combining these separate entities one common.

Business has changed as well. Aion is currently focusing on offering its financial services not in direct mode (so-called organic growth) but through partners in the BaaS model (Banking-as-a-Service), who enrich their services with Aion's financial products. From a technological point of view, this way of development also required the definition of new architectural standards (e.g. a consistent and efficient API for BaaS partners) and was a challenge in itself.

If you want to find out in detail what challenges we had, how we managed to address them and what we learned along the way, we invite you to our lecture.

Also check out our interview at Google where we talk about building a bank in the cloud.

Digital Transformation in practice

Modern technologies allow organizations to deliver more straightforward and more efficient services, reduce costs and be more competitive in the market. It's only some of the benefits that Digital Transformation delivers. But have you ever thought about what is behind it? How Digital Transformation is designed and who is involved to it? During the presentation, you will see how the design process of Digital Transformation looks like and the challenges of its implementation.

Piotr Stapp

How to become an architect in the cloud? So: Architecture + Cloud + FinOps = <3

I invite you to an interactive session where we will build together (it's not a mistake, your decisions will be key) a cloud solution design from A to Z.
In the room we will become architects, so our decisions for the project will be crucial. We will focus on, among other things:
- What components to use (including: hosting, databases, networking, security, ...)
- Is it more PaaS or IaaS? Or maybe a mix?
- How much will it cost? And most importantly why.
What will we work on? Azure, but if you are from AWS team or GCP team then your decisions will be even more important, because you don't have an opinion.

Recipe for a cloud team

Before we deliver any larger cloud project, we need a team. Building a successful one is not a trivial task, as we experience a shortage of cloud specialists on the market, and we all know that cloud computing has a steep learning curve.

How to build such a team from scratch? How to train and guide juniors? What is the role of cloud architects and technical leaders? How to share knowledge and experience within the team?

Based on my experience as a cloud architect and technical leader, I will share my answers to these and related questions to inspire and encourage you to find yours.

How to become Cloud Architect, CTO, Consultant?

CTO, Architect, Consult... all of those titles sounds like a great position – do all the cool stuff and drive technology adoption forward. Maybe Cloud Consultant is a good choice. They arrive at the site, drop the wisdom and knowledge, and disappear in the puff of the glory. This is the theory presented in the US made movies.
We’ve been there, done that, failed and win at the same time. In this session we will share our lessons learned about growing your career in the cloud technology world.
  • Good, bad and ugly sides of different career choices?
  • Does the cloud provider choice matters … or is it irrelevant?
  • What you will be expected to do at the staff engineering roles?
  • Is a CTO a most wise person on a team (and should it be)?
  • Is the CTO job for everyone? What to do next after being a CTO?
Sharing our combined 40yrs of experience in the technology and cloud we will give you our lessons learned.
The tips. The responsibility. The how-tos on the way there. Skills to learn and un-learn on the way.
Only battle-proven skills, tips and tactics of senior technical roles in the cloud.

Important: Workshops will take place in the same time and at the same venue as the presentation track. You can attend only one workshop at a time. 

Workshop tracks are exclusive to presentation track and other workshop tracks (meaning if you choose a workshop, you cannot switch tracks midday – mostly because workshops require continuity to provide value), but you still get to attend all the conference activities like networking, breaks, lunch, chill out, etc. No additional charge is required for choosing any workshops.

All presentations will be recorded and published, so if you choose to attend any workshop – you don’t have to be afraid of missing any speeches.

Modern hybrid environment with Azure Virtual WAN (VWAN)

  1. Fundamentals of buliding hybrid cloud
  2. Introduction to Azure VWAN
  3. Secure SD-WAN with Azure VWAN
  4. Security of WEB application in the public cloud

Azure Virtual WAN is an increasingly common choice for large, geographically dispersed environments. Thanks to Microsoft's solution, building a complex hub-and-spoke topology with implemented BGP has become extremely easy. The native integration of Fortinet solutions inside the VWAN HUB raises the functionality of such an environment to an even higher level. Fortigate deployed at the heart of such an environment allows you to build a secure hybrid cloud based on Azure Virtual WAN with full support for SD-WAN functionality. In this workshop we will learn how to build such a topology from scratch, starting with a single Fortigate deployed in Azure and ending with a hybrid cloud based on Azure VWAN.

Internet of Things in the Clouds

Learning the Internet of Things and cloud computing works best if we start practicing it sooner rather than later. In this workshop, you will learn about the Internet of Things, its variants – with similarities and differences, and possible use cases. Then you will see a few IoT cloud architectures. Finally, you will connect devices to the clouds, send messages and build a simple data processing solution.

This hands-on experience will be a good basis for learning more about this topic and finding a real-life IoT cloud project.

Hybrid migration scenarios between public and private cloud

In order to provide as much practical knowledge as possible, the event will test migration scenarios between "cloud A" and "cloud B" or the local Data Center. Users will migrate VMs from Azure to AWS, for example.

The presenters will show how to protect data in hybrid environments in practice. For example - a user uses Azure/AWS resources and at the same time a Virtual Data Center environment provided by 3S Data Center.

What should you do to adequately protect yourself during data migration?

As a bonus, securing the M365 cloud (Veeam Backup for Microsoft 365) using S3 (simple storage service) will be discussed.
