In OpenStack Juno release, L3 high availability in Neutron is implemented using Keepalived, which internally uses the VRRP protocol. It is an active/passive solution where a Keepalived instance is spawned in every router namespace and the instances communicate via a dedicated high-availability network, creating one per tenant. The IP addresses that are used in the… Continue reading IPv6 impact on Neutron L3 High Availability

How to go from a pile of servers and switches to OpenStack deployment?
Join Cumulus Networks to learn how to go from a pile of servers and switches to a working OpenStack deployment in 20 minutes with zero manual intervention. We’ll show automatic installation of switches using ONIE, automatic configuration of switches using ZTP (Zero Touch Provisioning), and PXE installing the servers, then use Puppet to install and… Continue reading How to go from a pile of servers and switches to OpenStack deployment?
OpenStack: Learn you some Ansible for great good!
Ansible is a Configuration Management System that is very simple to use, because of its straightforward and robust model for managing automation and it’s low barrier to entry for ease of use in both development and production. During OpenStack development, Ansible can be used in conjunction with Vagrant and Devstack to manage complex, multi-node development… Continue reading OpenStack: Learn you some Ansible for great good!
Building a Secure Multi-tenant Cloud for SaaS Applications: Challenges and Lessons Learned
Creating a secure multi-tenant cloud requires proper tenant isolation and access control, operational efficiency through automation and self-service provisioning, and on-demand service creation with dynamic resource scaling across key network and security functions. Delivering all of these requires a move to optimized software abstractions and policy-based architectures as existing infrastructures lack the means to support… Continue reading Building a Secure Multi-tenant Cloud for SaaS Applications: Challenges and Lessons Learned
Accelerating OpenStack Deployments with Enterprise Storage
Growth in open solutions such as OpenStack will outpace the traditional Compute and Storage segments and be the predominant driver for growth in the coming years. Accelerating this growth will require a diverse set of storage solutions as deployments migrate from POC to Production and into an Enterprise Data Center. This discussion will explore the… Continue reading Accelerating OpenStack Deployments with Enterprise Storage
OpenStack: One Keystone to Rule them all
Traditionally, the focus has been on configuring and deploying Keystone in single cloud / single data center. The enterprise clouds are generally spread across multiple data centers. What happens to authentication and authorization platform across multiple data centers? How do users from one data center access resources in 10 other data centers? At Symantec, we… Continue reading OpenStack: One Keystone to Rule them all
