Microsoff Azure wants a say in how switches operate.
NEC Director of Business Development Don Clark shares the latest SDN deployment lessons and guidelines in a special SDxCentral webinar based on the SDxCentral SDN Controller Report.
Fortinet-Cisco ACI integration uses SDN to reduce costs and improve service delivery in the cloud and in multitenant data centers.
In How Uber Scales Their Real-Time Market Platform one of the most intriguing hints was how Uber handles datacenter failovers using driver phones as an external distributed storage system for recovery.
Now we know a lot more about how that system works from Uber's Nikunj Aggarwal and Joshua Corbin, who gave a very interesting talk at the @Scale conference: How Uber Uses your Phone as a Backup Datacenter.
Rather than use a traditional backend replication scheme where databases sync state between datacenters to achieve a measure of k-safety, Uber did something different, what they do is store enough state on driver phones so that if a datacenter failover occurs trip information can not be lost on the failover.
Why choose this approach? The traditional approach would be much simpler. I think it is to make sure the customer always has a good customer experience and losing trip information for an active trip would make for a horrible customer experience.
By building their syncing strategy around the phone, even thought it's complicated and takes a lot work, Uber is able to preserve trip data and make for a seamless customer experience even on datacenter failures. And making the customer Continue reading
Many of the questions we frequently get are related to deploying applications and stacks into Amazon Web Services. Back in July, Ansible Government teamed up with partner DLT Solutions to host a webcast demonstrating the creation of a Red Hat stack in AWS entirely managed with Ansible. Watch it now and continue reading below for more information.
IT organizations look toward AWS for a number of reasons, but according to IDC, deploying applications in AWS results in a 64% lower TCO and 82% less downtime. Now let’s be honest. Who doesn’t like less downtime?
Red Hat is the leading Open Source provider for infrastructure and middleware solutions. Their industry-standard Red Hat Enterprise Linux and JBoss middleware are widely deployed in on-prem physical and virtual environments, and are the benchmark for stability, security, and performance.
But how can you leverage that power in AWS? With Ansible, it’s easy.
In the webcast, we demonstrate the deployment of a complete JAVA-based web application, including RHEL, JBOSS, and a load balancer. Once installed, we demonstrated how to use the same playbook that deployed the application to update the application. Better yet, these examples are available for you to start using and experimenting with today.
Here’s Continue reading
Friday afternoon, late, and the new system is finally up. Users are logged in, getting their work done, and you’ve just received an email from the CTO (your boss’ boss’ boss’ boss, probably), saying what a good job the team did in getting things up and running so quickly. For once, in fact, the system went in perfectly. There was no close to team breakups over which technology or vendor to use; there were very few unexpected items that crept into the budget, the delays were minimal, and you even learned a couple of new skills to top it all off.
Wonderful, right? The perfect unicorn project.
But before you break open that bottle of bubbly (or whatever cold beverage is your choice), or maybe pop up a bowl of popcorn and sit down to a long deserved break binge watching the shows you missed pulling this thing together, you need to ask one more question:
Did you strip and sand first? Or did you just paint right on top?
Or don’t you remember the time you tried to paint that old trailer that had been sitting in your back yard for ages? Sure, it was covered in rust, dirt, Continue reading
The post Worth Reading: A map of the Internet in the US appeared first on 'net work.
For a while now we’ve been hearing a lot of buzz about hyperconverged systems and we’ve been following it closely. We think what’s missing from these conversations is how critical the network is to the sustained success of these systems.
In our quest to build a simply better network, our key focus is on how to truly hyperconverge the network. And we do it by combining the latest in Ethernet switching with optical multiplexing to create a high performance, resilient, low latency and scalable data center network fabric. Unlike traditional leaf/spine approaches, Plexxi Switches are deployed as a single tier, eliminating cost and complexity while vastly reducing operational overhead so the enterprise can build true fabric agility to support the dynamic workload needs of hyperconverged nodes.
At VMWorld, Mat Matthews pointed out in his 5 Key Takeaways blog that hyperconverged solution providers are zoning in on the simplification of the consumption process around infrastructure. The silos are gone. Providers are recognizing that customers want to get new workloads up and running quickly without having to deal with getting storage, compute and networking to work together.
This is good news all around. We are seeing the realization that the network has Continue reading
Another week, another story from the SDN land, this time The Register reporting on AT&T plans. Even though there are almost no details in the story, the headline boasts that “SDN is eating vendors’ lunch”, prompting SDN hopefuls on LinkedIn groups to claim that “the promise of SDN is fast coming to fruition.”
Not so fast.
