What are the Multi-tenant SaaS architecture best practices? There is no cloud provider in a better position to support your containerized applications. The papers describe the technical and operational benefits of … It can serve as a starting point for architecting and securing workloads on AWS. As a result. The best practices we highlight here are aligned to the container lifecycle: build, ship and run, and are specifically tailored to Kubernetes deployments. With CloudWatch, users have a comprehensive view into the performance of their containerized applications, which means they can also troubleshoot issues quickly by drilling down into specific components. Implement the following runtime security measures: Complement pod security policies with AppArmor or seccomp profiles, Stream logs from containers to an external log aggregator, Audit the Kubernetes control plane and CloudTrail logs for suspicious activity regularly, Isolate pods immediately if you detect suspicious activity, Begin with a deny-all global policy and gradually add allow policies as needed, Use k8s network policies for restricting traffic within Kubernetes clusters, Restrict outbound traffic from pods that don't need to connect to external services, Encrypt service-to-service traffic using a mesh. The content is open source and available in this repository. You should also consider automating the creation of a configuration and any changes to it. Multi-tenancy 1. In my case, ‘Strict’ TLS mode is configured, which means listener only accepts connections with TLS enabled. Along the way, we have curated tips and best practices to make the best use of Kubernetes and Google Kubernetes Engine(GKE). Particularly, AWS App Mesh can help addressing areas of: When planning for App Mesh traffic encryption with transport layer security (TLS), you can provide a certificate to the Envoy proxy using either: In the steps presented below, I’ll use my own CA and certificates to enable TLS encryption for my Kubernetes application. As a cluster operator, work together with application owners and developers to understand their needs. Does each one have its unique and custom cloud software per customer? We need to have ‘magic glue,’ which does this job for us. In addition, many organizations don’t have the in-house expertise or capacity for this work. You can then apply it with the following command: The output confirms CA is ready to issue certificates: Following best practices for CA hierarchy would mean usage of at least two levels of CA structure with root CA and mid level subordinate CA issuing end certificates. Cert-manager provides granular management capabilities to issue individual certificates scoped to the virtual nodes. Now that have our CA ready, let’s issue certificates needed for App Mesh encryption. Leverage the power of Kubernetes on AWS to deploy highly scalable applications Provision Kubernetes clusters on Amazon EC2 environments Implement best practices to improve efficiency and security of Kubernetes on the cloud Book Description While working with customers on their projects, I often hear “I want to secure all my traffic with granular encryption-in-transit, close to application code, but decouple security from it.” That’s where AWS App Mesh can help. 11. This document presents a set of best practices to keep in mind when designing and developing operators using the Operator SDK. It is external certificate managed by ACM, visible by end user, and should be issued by the trusted CA. Listen in as we are discussing best practices and pitfalls that we have learned over the past 18 months. The following patch needs to added to an App Mesh virtual node definition at /spec/listener/0/tls hierarchy where 0 specifies the item number in a listener array: In the first part of the blog, I focused on an internal App Mesh service to service communication encryption so we apply above settings only to yelb-appserver, yelb-db, and redis-server virtual nodes. You have to think about all of the layers of your environment, beginning with your hosts. If you have a specific, answerable question about how to use Kubernetes, ask it on Stack Overflow. This is an add-on built on top of other AWS and Kubernetes security mechanisms. Microservices architecture remains popular today for modern app development because it enables developers to create loosely coupled services that can be developed, deployed, and maintained independently. Almost all data within the Kubernetes API is stored within the distributed data store, etc, which includes Secrets. Later, we will enhance encryption to entire communication path from browser to the application. Kubernetes best practices: Setting up health checks with readiness and liveness probes. Cert-manager supports issuing certificates from multiple sources both external such as: ACME based (e.g. Automation of security best practices: entire App Mesh configuration is auditable via APIs and metrics, which can be automated and integrated with a CICD framework of choice. For this demo, I will use root CA to directly issue certificates for App Mesh virtual nodes. Finally, Amazon continues to invest heavily in its Kubernetes services and capabilities. Best practices to deploy a Kubernetes cluster using Terraform and kops Stay tuned for future Kubernetes Best Practices episodes where I’ll show you how you can lock down resources in a Namespace and introduce more security and isolation to your cluster! In the first part of my post, default classic load balancer was used to expose service externally. After a request to the Kubernetes API has been authorized, you can use an admission controller as an extra layer of validation. In this blog, I will briefly discuss how to apply some of the Well Architected Framework Security Pillar design principles using App Mesh in a Kubernetes environment. Previous posts have discussed how to plan and create secure AKS clusters and container images, and how to lock down AKS cluster networking infrastructure.This post will cover the critical topic of securing … In this article, we will look at some Kubernetes best practices in production. Traffic is encrypted. You can automate your building and publishing processes with tools like AWS CodePipeline. Look out for these Kubernetes monitoring best practices when evaluating a Kubernetes monitoring solution. As a best practice, it is recommended to shift traffic from a virtual node with no TLS to a TLS-enabled virtual node using the App Mesh virtual router. Managing streaming data services and databases with Kubernetes. Modernizing legacy applications during a migration can be a complex endeavor, but the effort is well worth the investment if executed correctly. For more information on virtual gateways, peruse the App Mesh docs. I will illustrate this concept with an end-to-end tutorial showing how to implement it on an Amazon EKS cluster with App Mesh and open source cert-manager. On AWS, it is popularly known as EKS. Next steps should include granular RBAC configuration for Kubernetes secrets and setting correct IAM permissions for Envoy side car using IAM roles for service accounts. Validate node setup. Example: I once automated the use of AWS ALBs, ELBs and Route53 DNS via Kubernetes. Best practices for cluster isolation 1.1. Fortunately, there are many compelling reasons and useful tools for ensuring migration success. Once your containers are up and running, you have to think about how to optimize infrastructure for day-to-day operations. This is part 4 of our 5-part AWS Elastic Kubernetes Service (EKS) security blog series. Description ¶. Today, we are releasing best practices papers that detail how to architect VMware Enterprise PKS and Red Hat OpenShift on the VMware Software-Defined Data Center (SDDC). Save Your Seat! A certificate issued by your own Certificate Authority (CA) stored on the local file system of the Envoy proxy of a respective virtual node. You can then provision it with the following commands: We can verify that our Yelb application is working through https by checking the load balancer url in a browser: Additionally, the output below confirms TLS encrypted communication from NLB to virtual gateway and from virtual gateway to yelb-ui virtual node. Today, the question many are facing is how to migrate legacy applications into containers that thrive on the cloud. The container ecosystem is immature and lacks operational best practices; however, the adoption of containers and Kubernetes is increasing for … Best Practices for Virtualization When should you use full VMs, Docker, Kubernetes or lambdas? Kubeadm documentation often builds on the assumption that the distribution uses a traditional package manager, such as RPM/DEB.. Followed the instructions and deployed. Learn how AWS can help you grow faster. Save manifest as yelb-gw-deployment.yaml . We need to setup TLS mode and provide paths to certificate chain and its private key. Diagram of extended solution architecture is represented below: The configuration of a virtual gateway is very similar to a virtual node. There are certain best practices that you should consider for your Kubernetes multi tenancy SaaS application with Amazon EKS. He is passionate about containers and discovering new technologies. Third, containerized applications are efficient. In such a scenario, a certificate issued by a trusted public CA would be installed directly in the virtual gateway and managed together with remaining certificates by cert-manager. The loosely coupled nature of containerized apps allows developers to upgrade, repair, and scale discrete services. For managed node groups, you can use your own AMI and take the security responsibility on yourself. All our Kubernetes best practices. Use the right-hand menu to navigate.) Due to race conditions in delivering Envoy configuration to both the “client” and “server,” a brief disruption in communication can occur. We can now visit the Yelb web page, vote for our favorite restaurant, and verify if our traffic is encrypted with the following command: After a few visits to web page and a few votes, Envoy output confirms a proper TLS handshake for communication from yelb-ui to yelb-appserver: As well as, from yelb-appserver to both yelb-db and redis-server: So far so good. We also learned best practices for how to integrate EKS with other AWS products to enhance security and performance. In the case of a browser, there is a prepopulated list of trusted CAs (by operating system or browser vendor) but for internal microservice clients, you need to explicitly configure that list of trusted CAs. I will create new one and save it locally to the file. Operationally, it is important to know that cert-manager will handle the entire process of certificate renewal, and certificate updates are propagated to Envoy file system. Kubernetes can technically run on one server, but ideally, it needs at least three: one for all the master components which include all the control plane components like the kube-apiserver, etcd, kube-scheduler and kube-controller-manager, and two for the worker nodes where you run kubelet. Security is a critical component of configuring and … On top of that, the software tool helps IT teams manage the full lifecycle of their modernized applications. When building a production solution, all Well Architected Framework Security Pillar design principles mentioned in the beginning of the blog should be considered. Considerations for large clusters. It can be set as the default policy for all backends or specified for each backend separately. This page describes how to run a cluster in multiple zones. The first part – AWS Elastic Kubernetes Service: a cluster creation automation, part 1 – CloudFormation. For the purposes of this demo, I will generate a self-signed Certificate Authority managed by cert-manager as a Kubernetes resource. The following are our recommendations for deploying a secured Kubernetes application: Kubernetes has come a long ways since its inception a few years ago, but Kubernetes security has always lagged behind performance and productivity considerations. our customer achieved 50% faster deployment time. The role and best practice uses of StatefulSets and Operators. In many cases, engineers have refactor applications to prepare for containerization. Running containers in Kubernetes brings a number of advantages in terms of automation, segmentation, and efficiency. Key Features. I will use Helm to deploy cert-manager with the default configuration. They can migrate workloads using a lift-and-shift process, which we don’t recommend in most cases. Launch your application in a microservice environment: Run your image in AWS Fargate, AWS Elastic Container Service, AWS EKS, or a Kubernetes cluster on EC2 instances. After a request to the Kubernetes API has been authorized, you can use an admission controller as an extra layer of validation. Best Practices for Running Containers and Kubernetes in Production The container ecosystem is immature and lacks operational best practices; however, the adoption of containers and Kubernetes is increasing for legacy modernization and cloud-native applications. First, we need to provide existing or generate a new signing key pair for our own CA. In this article, we’ll explore some background concepts and best practices for Kubernetes security Clusters with a focus on secrets management, authentication, and authorization. The page presents a certificate but the browser cannot confirm its identity because CA is not trusted by operating system and the browser will trigger an alert about invalid certificate issuer. Best practices for advanced scheduler fea… AWS, EKS, Kubernetes Best Practices and Considerations for Multi-Tenant SaaS Application Using AWS EKS Today, most organizations, large or small, are hosting their SaaS application on the cloud using multi-tenant architecture. Securing containerized applications is crucial and requires a different approach than how you would secure virtual machines.

Running Kubernetes on Alibaba Cloud Running Kubernetes on AWS EC2 Running Kubernetes on Azure Running Kubernetes on Google Compute Engine Running Kubernetes on Multiple Clouds with IBM Cloud Private Running Kubernetes on ... Best practices. Once Kubernetes hit the scene, developers had a way to easily manage containerized applications (i.e., those built using microservices architecture). Here is a list of best practices. If you are considering migrating microservices to the cloud, choose AWS EKS. For more information on this refer to Certificate renewal section in the documentation. Kubernetes in production is a great solution, but it takes some time to set up and become familiar with it. Don’t stay at the surface, dig for deep system visibility. Kubernetes encourages logging with external ‘Kubernetes Native’ tools that integrate seamlessly to make logging easier for admins. They require less operational IT overhead to achieve optimal computing. For the purposes of this blog, I’ll use the Kubernetes internal certificate authority managed by cert-manager. In this step, we are also mounting a secret with the certificate files needed for Envoy configuration. Emil is a Partner Trainer at Amazon Web Services. Not all legacy applications will fit neatly into containers. We will create a new certificate and secret unique for the Yelb virtual gateway configuration. One of such advantages is the possibility to add transparently traffic encryption between modules of existing modular application without need to modify it. Application code can be simpler as advanced communication patterns are realized “externally” by the service mesh. Integration with logging and monitoring tools needs be applied. It is important to remember that, by default, all secrets within namespace are available to all pods/deployments. January 11, 2021. Then, you can secure your container images and pods at runtime. For the encryption of ingress traffic coming from outside of App Mesh (e.g. Perhaps, the most useful and trendy tool which has come in this space is Kubernetes. In parallel to the step-by-step guide, full configuration files are available in the App Mesh examples repository. He enjoys helping customers and partners on their journey to the cloud.

At this point, we have all components available and we are ready to start connecting the dots and build an App Mesh encryption solution. You can then deploy it with the following command: As the next step, we have to label the yelb namespace with information on our newly created virtual gateway: Finally create the deployment with an Envoy container, which will be mapped to our virtual gateway. We especially enjoyed learning more about how to leverage Kubernetes and optimize infrastructure for containerized applications on AWS. Click here to return to Amazon Web Services homepage, Well Architected Framework Security Pillar, The Well Architected Framework (WAF) security pillar, AWS Certificate Manager Private Certificate Authority (ACM PCA). traffic to yelb-ui), we will create an App Mesh Virtual Gateway and apply similar TLS configuration in the next paragraph of the blog. Running Kubernetes in AWS enables you to run and manage containers on EC2 cluster instances. In sum, rebalancing Kubernetes clusters is about performing best practices one, two, and three (pod rightsizing, node rightsizing, and autoscaling) in an integrated way and on an ongoing basis. The sheer number of available features and options can present a challenge. Applying best practices helps you avoid potential hurdles … In this post I provided you with an overview of the steps needed to configure App Mesh encryption with certificates using the Kubernetes-native open source project cert-manager. All rights reserved. Yelb microservices could establish internal TLS communication but none of them verified the identity of CA issuing certificate. As a Kubernetes security best practice, network policies should be used specifically on cloud platforms to restrict container access to metadata hosted on instances (which can include credential information). See AWS App2Container for more information on how to containerize your Java or .NET applications to run on EKS. This is a lightweight version of a broader Cluster Federation feature (previously referred to by the affectionate nickname … To make sure your CRD conforms to the Kubernetes best practices for extending the API, follow these conventions.

Now, the majority of the developer community is using it to manage apps at scale and production to deploy. ... For the instruction about specifying an AWS CloudFormation template ... such as a new AMI or Kubernetes version, you need to change the previous settings in the template again. Let’s face it. I will use the default client policy for all backends. We will begin with configuration of TLS server part. Now we need to patch virtual node definitions with the below config: Again, after visiting the Yelb web page and playing with it, we can verify our service is working properly by seeing the increased counters of ssl handshake. Kubernetes was released in 2014 on the heels of the microservices movement. In this blog, we discuss how there are multiple benefits of Kubernetes on vSphere, such as Availability, Interoperability, Scalability, and Performance. AWS will actually manage your Kubernetes control plane on your behalf, including securing all control plane components. Running in multiple zones. Save manifest as ca-issuer.yaml. 2. This will enforce setting TLS communication only with upstream services, which present a certificate signed by the client’s trusted CA. Check out our webinars! We adopted these best practices in our own SaaS deployment that runs Kubernetes on Google Cloud Platform. The more interesting part is flow between load balancer and App Mesh. Amazon Elastic Container Service for Kubernetes, Amazon EKS, provides Kubernetes as a managed service on AWS. Don’t forget to check out our previous blog posts in the series: Part 1 - Guide to Designing EKS Clusters for Better Security; Part 2 - Securing EKS Cluster Add-ons: Dashboard, Fargate, EC2 components, and more; Part 3 - EKS networking best practices Openssl or cfssl tools can be used for it. Kubernetes is a powerful orchestration tool, and with this power comes the responsibility to correctly configure the system to operate in your best interest. Fortunately, AWS makes this easy with services like Amazon CloudWatch. Introduction Kubernetes 1.2 adds support for running a single cluster in multiple failure zones (GCE calls them simply "zones", AWS calls them "availability zones", here we'll refer to them as "zones"). Engineers can develop and deploy applications faster to achieve overarching business goals. The configuration is saved to yelb-gw-service.yaml file. ClearScale is a cloud systems integration firm offering the complete range of cloud services including strategy, design, implementation and management.
