Oracle SOA suite and Coherence dehydration

Open vStorage is an open source software that transforms object storage like OpenStack Swift into block storage for virtual machines (VMs). It acts as a middleware layer between the hypervisor and object store, presenting block storage to the hypervisor while storing data in the object store as time-based containers. This allows VMs to leverage the scalability and low cost of object storage. Open vStorage provides caching to improve performance and integrates with OpenStack through the Cinder volume plugin to enable common functions like snapshots. It provides a single, scalable storage platform for both VM block storage and image/backup object storage.

Kafka security includes SSL for wire encryption, SASL (Kerberos) for authentication, and authorization controls. SSL uses certificates for encryption during network communication. SASL performs authentication using Kerberos credentials. Authorization is provided by pluggable authorizers that define access control lists controlling permissions for principals to perform operations on resources and hosts. Securing Zookeeper with ACLs and SASL is also important as Kafka stores metadata there.

Scaling out a web application involves adding redundancy, separating application tiers across multiple servers, implementing load balancing, caching content, and monitoring performance. Key aspects include mirroring disks for redundancy, moving services to separate application servers, using load balancing schemes like DNS round-robin or load balancers, solving session state issues through sticky routing or database storage, and caching dynamic content to improve performance. Monitoring the environment is also important to detect failures or bottlenecks as the infrastructure scales out.

This document provides an overview of Gen-Z, a new interconnect architecture proposed to address challenges with increasing data growth, flat memory capacity, and the need for real-time data insights. Gen-Z is designed to provide high bandwidth and low latency memory semantic communications across systems. It breaks the traditional processor-memory interlock by introducing a split controller model. This allows for more flexible and composable solutions that can leverage different memory technologies. The Gen-Z Consortium is developing open standards for the architecture with the goal of enabling innovation through an open and non-proprietary approach.

Proxies are building blocks of high availability setups for MySQL. They can detect failed nodes and route queries to hosts which are still available. If your master failed and you had to promote one of your slaves, proxies will detect such topology changes and route your traffic accordingly. More advanced proxies can do much more, such as route traffic based on precise query rules, cache queries or mirror them. They can be even used to implement different types of sharding. In this webinar we talk about support for proxies for MySQL HA setups in ClusterControl: how they differ and what their pros and cons are. And we show you how you can easily deploy and manage HAProxy, MaxScale and ProxySQL from ClusterControl during a live demo. AGENDA Introduction Why use a proxy layer? Comparison of proxies - the pros & cons - HAProxy - MaxScale - ProxySQL Live demo of proxy support in ClusterControl SPEAKER Krzysztof Książek, Senior Support Engineer at Severalnines, is a MySQL DBA with experience managing complex database environments for companies like Zendesk, Chegg, Pinterest and Flipboard.
