Managing and Monitoring SLA Domains at Global Scale

In my previous post, I went into the complexities that funnel into building Service Level Agreements (SLAs) that exist between consumers and providers of an IT service. This friction can be greatly assuaged by decoupling the agreed upon policy’s intent from the actual execution of backup jobs. It allows administrators to abstract away much of the low-end fuss required to build and maintain data protection, instead focusing on adding value at a more strategic level across the organization. Let’s now move the story forward to discuss how consumers can easily determine if their SLAs are being honored. At a high level, SLA Domains are constructed using Recovery Point Objective (RPO) and retention values. The RPO is essentially asking how much data loss the consumer is willing to tolerate, while the retention input determines where the provider will store data (on-premises or elsewhere). To understand SLA compliance, it’s important to look at the entire set of backup jobs to ensure all facets of the RPO are being met for an application. This goes beyond looking at the number of total backups held by the system, as an RPO is often expressed as a quantity of hourly, daily, weekly, monthly, and yearly…

Introducing Atlas, Rubrik’s Cloud-Scale File System

Rubrik is a time machine for virtualized infrastructure. It periodically takes snapshots of an enterprise’s virtual machines (VMs), allowing for instant recovery to a previous point in time. In order to efficiently store the entire history of a VM, it represents each snapshot as a delta, with each delta containing only the data which has changed since the previous snapshot. Atlas is Rubrik’s Cloud-Scale File System at the foundation of the storage layer. It was designed specifically to support the time machine paradigm. Conceptually, Atlas stores a set of versioned files: each VM is a file, and each snapshot a version of that file. Internally, Atlas stores each snapshot as its own file, with the first being a full copy of the VM and each subsequent an incremental delta from the previous. One of the reasons we chose to create Atlas was to have fine grain control of replica placement in order to co-locate related data. Almost all operations in our system involve operating on the content of a VM. In order to make these operations efficient, Atlas places entire file replicas on specific nodes, rather than spreading the data blocks backing the file randomly throughout the system. Put another…

Decoupling Policy from Execution with SLA Domains

Successful enterprise architects are able to pull functional design elements from key stakeholders to abstract requirements, constraints, and risks. Much of this work involves translating business needs into technology decisions and then deciding upon the right vendor solutions to provide for the design. In this blog post series, I’m going to focus on addressing Service Level Agreements (SLAs) to ensure that the business is equipped with the runway it needs to tackle operational challenges and protect applications. Many organizations that I’ve consulted with were forced to take a good, hard look at their SLAs (or lack thereof) in order to craft a strategic plan for the future. At the heart of any quality SLA is fairness. Both parties – the consumer and the provider of a service – must agree on a mutually beneficial statement for long term success. The end goal is to abstract the minutiae of a technical design away from the consumer. Such as this WordPress platform: I really don’t concern myself with the back end infrastructure, I just want to consume the service and know that it’s being protected. An SLA is a method for me to define guard rails around data loss and availability while…

The Future is Inside This Box

Searching for files in seconds, validating backup jobs, and more importantly, taking vacation. Jaime Huizar, Senior Architect at Power Integrations, talks about the benefits of adopting Rubrik early on. How did you become an Infrastructure Architect? I’ve always loved technology and tinkering with things. As a kid, I was fascinated by computers – taking them apart, putting them back together. Working in IT was a natural path to do what I love: test-driving and using the latest technologies. I’ve been in the business for 20 years. What does Power Integrations do? We’re a semiconductor manufacturing company that specializes in conversion from AC to DC, and vice versa. We can be found anywhere from a cell phone charger to a locomotive to a windmill. Tell me more about how your team supports Power Integrations? Our charter is to keep operations running 24/7 around the world. Any PI (Power Integrations) employee needs to be able to access information any time of the day globally. For us, that means keeping a pulse on the latest technology trends. For example, we were an early adopter of virtualization and started using VMware in 2007. Any technology that can give our business a competitive advantage and…

Welcoming Chris Wahl to Rubrik

Today at Virtualization Field Day 5 (#VFD5) we were thrilled to welcome the newest member of the Rubrik family, Chris Wahl. Chris is a respected voice in next-generation data center technologies and has earned his reputation in the community over the past decade with hands-on experience with enterprise infrastructure design, service orchestration, and data center automation. However, many of us know Chris through his blog, Wahl Network, which ranks in the Top 10 Virtualization Blogs and has earned the favorite independent blogger designation for three years running. He’s also led and presented at VMware User Groups (VMUGs) across the globe, co-authored Networking for VMware Administrators, and holds two VMware Certified Design Expert (VCDX) certifications. The Opportunity Ahead So, why did Rubrik and Chris join forces? “For far too long, backup and recovery has been a neglected corner of the data center,” Wahl says. “Recent technology breakthroughs have opened the door for Rubrik to create a simple solution that abstracts away the vast majority of data protection road blocks. It’s an extremely exciting time to be working in this space.” We couldn’t agree more. Getting the Word Out on Rubrik There’s no excuse for complex, brittle architectures, frustrating user experiences and worst of all…
