Back at Storage Field Day 16 in Boston, Zerto presented their VM replication software. It’s a block level, continuous hypervisor based replication, using a journal to log I/O in a VCR-like fashion. This enables you to rewind to any point in time that’s covered in the journal, and recover your VMs to that exact state. Zerto’s plans are a bit grander than “just VM Replication” though… they aim to cover the complete IT Resiliency market.
Moving to the cloud comes with many advantages. There’s the obvious advantages: if you put all your servers or services in the public cloud, you do not need your own datacenter. Provisioning rates are typically pretty fast, so this improves the time needed to spin up a new service. Plus pretty much every cloud is based on a “pay as you use/grow” billing model, giving you predictable costs.
Different public cloud providers charge different prices for services. So what if you could use the best value components from each cloud provider? Say hello to the multi cloud.
This is a long overdue post covering Dell EMC World 2017 in Las Vegas and the announcements that were made during the event. I’ll recap some of the topics that resonated most with me, namely that cloud computing is not a place but a way of doing IT. Secondly, I spoke briefly with some of the Dell EMC server guys whom give me hope that the Dell 14th generation servers are a big step up from previous experiences. Finally, I’ll share a bit of insight in what the Dell EMC Elect picked up during an interview with John Roese, and will link to a few posts from friends that attended Dell EMC World 2017. Maybe it’s a bit more of a “Dear diary,”-style post, so hang in there.
There’s no denying that off-premises cloud services are growing. Just look at the year-to-year growth of big public cloud providers. There’s big potential if you focus on two aspects of cloud. The first is speeding up access to data that is potentially not located in the same city or even geographic area. The second is supporting new protocols and storage methodologies that are suited for cloud native applications. One player in this area of IT is Avere, which aims to connect on-premises storage and compute to their siblings in the cloud.
When the news about the Dell and EMC merger became public last year, I was somewhat skeptical. I’ve had some really sketchy experiences with Dell servers and storage products, so it didn’t feel like a step forward. At the same time there was the organizational and support aspect. Mergers usually result in confusion for both sales processes and us people in the field having to glue all the products together. Not something I was looking forward to.
Lo and behold: I got an invite from the EMC Elect program to attend DellEMCWorld in Austin, Texas! This was my chance to fly over there and experience the merger announcements firsthand, plus ask questions. So I did! And I have to say: I was impressed.
A long, long time ago when public cloud IaaS (Infrastructure as a Service) was still relatively new I was doing some contract work for a big international company. One of the tasks for the department was an IaaS proof of concept: does offloading servers to the public cloud result in cost savings? Long story short: the PoC was halted after several months because the AWS IaaS offering was prohibitively expensive and inflexible. We had enough systems and data to keep a team of qualified engineers busy and to get good purchasing discounts. An additional problem was the very rigid service catalog: there weren’t that many flavors of machines available back then and custom machines were either not possible or even more expensive.
Fast forward to 2016 and I’m looking into public/private/on-premises IaaS again for a different company. Prices have dropped, but there are still some things to keep in mind when considering a move to the public cloud IaaS models.
Several years ago cloud computing became the hottest thing in IT. You couldn’t read an article or product description without being smothered with ‘cloud’ every other sentence. In fact, many organizations renamed their product and service offerings to include cloud. If you didn’t have ‘cloud products and services’, you were going to lose business.
I’ve noticed that there’s still a surprising amount of IT people that don’t fully comprehend what cloud computing means. Is it a location or a concept? Are there different types and layers of cloud computing? Lets see if we can explain a few of the more common options…
