Apache Ranger™ is a framework to enable, monitor and manage comprehensive data security across the Hadoop platform.
The vision with Ranger is to provide comprehensive security across the Apache Hadoop ecosystem. With the advent of Apache YARN, the Hadoop platform can now support a true data lake architecture. Enterprises can potentially run multiple workloads, in a multi tenant environment. Data security within Hadoop needs to evolve to support multiple use cases for data access, while also providing a framework for central administration of security policies and monitoring of user access.
Chaos Engineering is a great idea — build an automated solution/tool to randomly attempt to break a system in some way; ultimately to learn how the system behaves in such situations. Then you can use your newfound knowledge to find ways to make the system more fault tolerant during these failure conditions in the future.
Cloud platforms provide a wealth of benefits for the organizations that use them. However, there’s no denying that adopting the cloud can put strains on DevOps teams. Developers must use microservices to architect for portability, meanwhile operators are managing extremely large hybrid and multi-cloud deployments. Istio lets you connect, secure, control, and observe services.
First, download Istio release version, unzip the package and enter the directory.
Second, verify installation environment
bin/istioctl verify-install
Next, deploy Istio and select the demo profile which enable many features like tracing/kiali/grafana
bin/istioctl manifest apply --set profile=demo
Then, check Istio pods’ status, make sure all the related pods are running
Istio Commands
authn: Interact with Istio authentication policies
authz: (authz is experimental. Use istioctl experimental authz)
convert-ingress: Convert Ingress configuration into Istio VirtualService configuration
