Beyond a datacenter and hardware fault tolerant strategy (part 3/3)

Finally, we are in the last part. My previous note has almost finished with the sentence: “Most of the customers defines their application instances based on this non-redundant logical architecture”. The next picture illustrate the exact meaning of this. All the redundancy at the facility/hardware means nothing when you lose a virtual instance cause to a human mistake. You will have to recover it from the last … Continue reading Beyond a datacenter and hardware fault tolerant strategy (part 3/3)

Beyond a datacenter and hardware fault tolerant strategy (part 2/3)

Ok, I’ve brought in my previous note a short overview how Tier IV datacenter are designed to deliver the best in class technology to take care of your IT stuff against any electrical or physical failure into the facility. Later on, I’ve mentioned if you want to get instances from any of our clouds, you bet that any of our configurations has got the required redundancy to support any … Continue reading Beyond a datacenter and hardware fault tolerant strategy (part 2/3)

Cloud Computing’s Densities are changing Datacenter’s Energy Design

When we started with our cloud architectures some years ago, LATAM’s market was just looking to move traditional systems into high density virtual private servers. Now, the amount of applications distributed among lower density instances is starting to increase to a such point that the density of energy per rack has increased three times. New application’s architectures requires several layers of components: app servers, web servers, … Continue reading Cloud Computing’s Densities are changing Datacenter’s Energy Design

The Best #DDoS protection: #DevOps

We’ve started selling online VPS on #OpenStack two years ago when #DDoS wasn’t so Distributed. Now, it’s our number one concern in our services and we’ve done lot of changes over the time in our Cloud Infrastructure to protect ourselves. It’s a Pity, that an important part of these instances are bought to attack outside sites and we were in the duty to suspend their services – we don’t want … Continue reading The Best #DDoS protection: #DevOps

How to design your SAP HANA disaster recovery | CHANGE as a Service

Awesome! Emilio thanks for sharing this really good post. IMHO the best way to replicate is thru HANA itself with Bandwidth Optimizers on both sides. also, you have to consider the rest of the applications like BO, or maybe, it’s a suite on HANA, it would be nice how this kind of architecture change. Thanks again for so awesome note. This scenario will work for both … Continue reading How to design your SAP HANA disaster recovery | CHANGE as a Service

There’s Real Magic behind OpenStack Neutron

Really easy to create a new post on any blog – the most complex part is to think about the content – you can do it through a couple of clicks on your laptop, or from your phone/tablet, or just reblog other interesting posts from some mates. The same thing happens with OpenStack, you can create Servers instances, routers, subnets, firewalls, VPNs, Load Balancers through … Continue reading There’s Real Magic behind OpenStack Neutron

Software Defines Options for your Cloud’s Network Services

In spite of the long list of products or open-sourced SDN (Software Defined Networks) solutions to opt these days, the finally amount is limited due to stability and scalability reasons. Worst is if you think trying to bring network resources to some applications that will require direct support from vendors; limitations include components like Hyper-Visors. Despite you can run any of these apps over these technologies … Continue reading Software Defines Options for your Cloud’s Network Services

What do I have to choose to efficiently store, protect and manage my private cloud’s data?

The amount of available storage systems in the market have increased in my radar during the last months therefore the complexity to choose one of them – I am personally afraid of choosing one now and regret it later, aren´t you? –  The storage ecosystem is changing so fast that probably if you select something now, the criterion that you have just used won’t work few months later. This new trend of software defined something that has blessed the storage field and now … Continue reading What do I have to choose to efficiently store, protect and manage my private cloud’s data?
