Appvia exists to help software engineering companies accelerate and scale using the best cloud-native technology available today. Without wasting resources, exposing themselves to unnecessary risks or becoming bogged down in the search for specialist skills. 

Wayfinder, Appvia's Cloud Native Application Platform, enables organisations to securely develop and deploy applications by providing a fully multi-cloud Kubernetes platform, empowering businesses to scale quickly and securely in the cloud.

PodSecurityPolicy exists in Kubernetes to provide security controls for pods. PSPs are deprecated in 1.21 (April 2021) and will be removed entirely in 1.25 (expected around April 2022). This article explains what PSPs are and its alternatives. We created a PSP migration tool that translates existing PSPs to 3 different policy engines. This blog will also present why using policies might be making things worse not better and how these checks could be carried out more efficiently with good CI/CD practices.

PodSecurityPolicy is Dead, Long Live...?

Kubernetes Fundamentals

Understanding and implementing the fundamentals of proper application development processes is key to your success in the public cloud space. Kubernetes offers the reality of true application scale and dynamic resource management, however, your application must be created in a way that supports it. The 12-factor application methodology is the basis for developing a truly scalable application that is ready for the public cloud platforms.

In this first webinar of this series, we’ll dive into the 12-factor application methodology and discuss the key points that directly relate to a successful kubernetes cloud application.

12-Factor Application Development for K8s (and why its a BFD)

Following our webinar “Do You Even Need Kubernetes Anyway” - you’ve decided that you do and have now started to wonder if you can handle this.

Kubernetes out of the box is a big undertaking. You need to grow a priesthood of people to manage that and it’s too complicated and expensive. The providers have offered a level of simplification with products that provide a pipeline into Kubernetes for your apps - which makes things a lot simpler for you. We then offer yet more simplification with our two-part series Kubernetes from 10,000 ft. 

Pt 2: Getting Started - understand the overview of K8s architecture and how to deploy applications using Kubernetes. Live Q&A with our Kubernetes experts following the talk.

Kubernetes from 10,000 ft: Part Two - Getting Started

Following our webinar “Do You Even Need Kubernetes Anyway” - you’ve decided that you do and have now started to wonder if you can handle this.

We then offer yet more simplification with our two-part series Kubernetes from 10,000 ft. 

In Pt 1: The Anatomy of Kubernetes, we'll explain how Kubernetes work and how to get started. If you are new to K8s, this webinar is ideal just to understand the basics of how to run your microservices resiliently and at scale, and then how containers and K8s help with that. Live Q&A with our experts following.

Kubernetes from 10,000 ft: Pt 1 - The Anatomy of Kubernetes

Teams using Kubernetes often are like people moving into a pristine new flat in a tower block: every flat was built totally identical and vanilla, and anyone coming in to work on them would know exactly where everything was like power outlets, phone lines, etc. But teams do the natural thing many do which is to make it their own - or a snowflake, which is to say something totally unique and possibly non-reproducible. 

The consequences of this vary but are often observed when you have an issue and you need to explain to whoever comes to fix it all the weird wonderful things you can remember you did so they can help you. 

In this discussion-style webinar, Chris Nesbitt-Smith and Graeme Colman bring their vast experience of this problem to talk through the many angles of this, from addressing recruitment, onboarding issues to operational challenges.

Is it time to put your pet Kubernetes down?

Part one of our series "Is Being a Platform Manager the Most Stressful Job in the World?!"

In this webinar we will be talking to Tim Grant, a Platform Engineering lead working with a large financial institution. We will be discussing how to avoid platform teams becoming a bottleneck in the application delivery process, what “tools” can be used to identify and rectify wait times in the process, and what changes have been implemented to reduce toil.

Is It Done Yet? Where To Invest Time and Money

Infrastructure operators that are part of a centralised team are responsible for implementing a consistent and repeatable infrastructure provisioning solution that uses cloud best practices to meet the applications' requirements on a cloud provider.

They may choose to create, maintain and vendor infrastructure compositions but there is no simple and consumable way to package and present back to application developers to self-serve cloud resources without them spending time on learning the cloud infrastructure details and tools instead of applications.  

In this demo style webinar, Appvia Solutions Architect Yas Jaffoo talks through the problem he saw and how he solved it using Helm to create cloud resources.

In this webinar, you will learn:
 - How to create an AWS S3 bucket with Helm
 - Ways of working & separation of concerns
 - How this simplifies app development in the cloud

Enabling Developer Self-Service with Terraform & Helm

Second in our Kubernetes Fundamentals series:

Kubernetes is hard. Let’s build something easy! In the second webinar in this series, we’ll do what all good technology folks do and build our first ‘Hello World’ application for Kubernetes. Building on the fundamentals in the previous webinar, we will showcase how to create, deploy, manage, and destroy your first K8s application on public cloud. We’ll cover ideas such as: 

- What are the common design patterns? 
 - What are the potential pitfalls? 
 - What should you consider security-wise when developing in a microservices architecture. 
 - How the heck do I monitor this thing?

Your first “hello world” K8s app

Kubernetes has been the de-facto standard for container orchestration for years, because of its powerful, built-in capabilities for security, logging, scaling etc. 

Kubernetes offers a variety of security controls, but using a default configuration exposes a wide attack surface and leaves you open and vulnerable to potential risks. It’s also extremely complicated. Especially if you’re just getting started, and even if you’re not, navigating Kubernetes is hard to get your head around. 

Hope isn’t lost if you’re using a default configuration: There are plenty of simple best-practice changes you can make to quickly and easily improve the security posture of your platform. This webinar will go through the top five changes you can make immediately that will have the biggest impact on your overall security posture. 

Why trust us? 
The founders of Appvia have worked with Kubernetes in highly regulated, highly secure environments since 2016, contributing heavily to innovative projects such as Kops and fully utilizing Kubernetes ahead of the curve. We’ve mastered Kubernetes, and experienced its complexities first-hand, so our customers don’t have to.

5 Things That Will Improve Your Kubernetes Security Posture

Brought to you jointly by Appvia and Microsoft 

All of us have experienced a global disruptor that none of us saw coming. As the world emerges into a new digitally transformative era, businesses have discovered that they are critically dependent on being cloud-native and becoming agile in order to meet their customers’ changing needs. 

With a public cloud such as Azure, businesses have a wealth of tools and best practices to guide them through to successful outcomes that being cloud-native offers. But they have become stuck in the mud, and unable to move forward because they do not know how to effectively use these tools. If businesses can pull themselves out of this mire, they could be set onto a path to true innovation. But how do they do this?

In this discussion-style webinar, brought to you by Appvia and Microsoft, we continue the conversation into how customers realize the true value of cloud. Microsoft will share the challenges their customers are seeing struggle in adopting Kubernetes on Azure, and how Azure and Appvia collectively help businesses realize the true potential of cloud-native with AKS.
