Last week Amazon Web Services and Rackspace notified customers that their servers would be rebooted as a part of Xen hypervisor patching. This is the second time that AWS has scheduled reboots as a part of its cloud infrastructure maintenance, and AWS published guidance for building applications resilient to reboots and restarts.
Udi Dahan describes how we in a Service-Oriented Architecture (SOA) where client-side components for one service runs in the same process as components for other services can collect several logical calls into one larger physical call to avoid the high cost, in terms of client to server communication, that otherwise could be substantial.
The Particular Service Platform has four headline components: ServiceMatrix, ServiceInsight, ServicePulse, and the well-respected NServiceBus. Over the next few weeks, we’ll be looking at each in turn starting with ServiceMatrix, their SOA design tool.
We should build systems more loosely coupled to achieve properties like robustness, resilience and scalability, Udi Dahan emphasizes in a recent presentation discussing how we can model our systems using more event-driven and asynchronous patterns and some of the challenges developers face when introducing these principles and patterns into development.
Recent research has made it increasingly clear that developers hold the key to cloud adoption, and Rackspace is trying to make themselves an attractive option. The Rackspace Developer Discount program is designed to lower the barrier to entry and follows similar efforts by AWS and Microsoft.
Latest Rackspace developments include .NET SDK, PowerClient – a PowerShell-based management tool – and PHP mobile back-end.
Rackspace has transferred all the OpenStack code, trademarks and related intellectual properties to the OpenStack Foundation, leaving the cloud computing platform into the hands of the community.
NServiceBus 3.0 was recently released and InfoQ talked to Udi Dahan, the creator of NServiceBus, about the new features of the latest release. One of which is the RavenDb integration, a fairly new document data store written in .NET and created by Oren Eini (Ayende). InfoQ also took the opportunity to ask Ayende some questions and what the integration means for his own Rhino Service Bus.
RightScale, a company providing unified access to multiple clouds, has announced a new release of their cloud management platform consisting of a new MultiCloud API, a new Add Server Assistant, and a Community Translations.
A number of announcements around open hardware specifications and open source cloud infrastructure and platform software solutions by collaborators in the OpenStack initiative were made in the past 2 weeks. How does all of them stack up together?
Today, developers and system administrators may download Rackspace Cloud 2.0 for iPhone, iPad and iPod Touch from the Apple App Store. The new universal iOS application allows developers and admins to manage their Rackspace Cloud deployments as well as customize OpenStack Clouds.
Yesterday Josh Odom announced the beta release of Cloud Load Balancers for the Rackspace cloud computing stack. This release comes with their Fanatical Support and a documented API for implementation and management load balancing on their stack, Cloud Servers.
Three recent announcements highlight the evolving cloud ecosystem in favor of openness and standards. Red Hat has moved its Deltacloud effort to the Apache Incubator, Rackspace has made its Cloud Files code open source, and the Distributed Management Task Force (DMTF) has released two documents laying out the essential functions for cloud computing and descriptive language for them.
