Lightning in the Clouds, Big Data

Venture into the clouds, but prepare for lightning

Cloud computing has been marketed as one of the key advances in technology and every day we hear about new areas where cloud services are being utilized. Cloud is the bright shining star that is being leveraged for it's elastic, on-demand, resource pooling capabilities. However there have been Cloud outages recently that have adversely impacted businesses. These outages highlight the risks of the Cloud and bring into focus that such risks need to be effectively managed. Cloud outages are like lightning in the Clouds, lightning can cause problems where it strikes and preparation is important to avoid damage.

This year Amazon, Salesforce, Google, Gmail, Google App Engine, Microsoft Office 365, Azure had outages that impacted businesses. During this holiday season, some Netflix subscribers were hit with an outage on Christmas Eve that was caused by Amazon cloud servers.  Amazon tracked the issue to Elastic Load Balancing, that enables spreading traffic across many servers.The wasn't good timing for the outage as subscribers were looking forward to watching movies during this period. Microsoft Azure storage had an outage during the holidays that impacted the management portal. Big Data services and  providers have also reported access issues.

There are many ways of minimizing risks associated with such outages.  The key is to distribute the load that comes in and to have redundancy, so that failure in one area can be picked up by another area. There are many approaches to achieving such redundancy. One way to do this is to distribute systems across locations so that if one location is down, the other one can pick up the load. Multiple location failover can be more expensive, hence the costs have to be weighed against the benefits and availability requirements. Another approach is to have back up clouds for applications with requirements for high availability, to which traffic can be diverted to reduce the risks of downtime in a specific cloud. Again, this can be more costly compared to having the regular clouds. A similar approach is to have the applications spread out across many clouds, so that if there are downtime issues, not all applications go down at once.   If applications are located in many clouds, this can enhance availability if one of the clouds goes down.

It is important to have adequate monitoring for applications and cloud services to be informed when the services are down and to take necessary actions. Both availability and performance monitoring should be conducted to identify any problems. Availability monitoring tracks if the applications and services are up and running, performance monitoring looks into  performance metrics such as response time for applications and services. Availability and performance should be specified for services and applications based on the requirements.  Key events have to be identified for monitoring and specific alerts have to be set up and as soon as these alerts send notifications, specific actions should be taken.  All these aspects should be defined in a plan that lays out all the details of events and related actions so that any outages can be handled effectively. Preparation is key to ensure the proper actions are taken to address and recover from any such issues. The risks related to Cloud outages can be managed by having the proper approaches for availability and performance, regularly monitoring and taking appropriate actions in a timely manner.

Your homes and cars can be automated and self-serviced. Why can't your storage? From simply asking questions to analyze and troubleshoot your infrastructure, to provisioning storage with snapshots, recovery and replication, your wildest sci-fi dream has come true. In his session at @DevOpsSummit at 20th Cloud Expo, Dan Florea, Director of Product Management at Tintri, provided a ChatOps demo where you can talk to your storage and manage it from anywhere, through Slack and similar services with...
"As we've gone out into the public cloud we've seen that over time we may have lost a few things - we've lost control, we've given up cost to a certain extent, and then security, flexibility," explained Steve Conner, VP of Sales at Cloudistics,in this SYS-CON.tv interview at 20th Cloud Expo, held June 6-8, 2017, at the Javits Center in New York City, NY.
For over a decade, Application Programming Interface or APIs have been used to exchange data between multiple platforms. From social media to news and media sites, most websites depend on APIs to provide a dynamic and real-time digital experience. APIs have made its way into almost every device and service available today and it continues to spur innovations in every field of technology. There are multiple programming languages used to build and run applications in the online world. And just li...
If you are thinking about moving applications off a mainframe and over to open systems and the cloud, consider these guidelines to prioritize what to move and what to eliminate. On the surface, mainframe architecture seems relatively simple: A centrally located computer processes data through an input/output subsystem and stores its computations in memory. At the other end of the mainframe are printers and terminals that communicate with the mainframe through protocols. For all of its appare...
There is a huge demand for responsive, real-time mobile and web experiences, but current architectural patterns do not easily accommodate applications that respond to events in real time. Common solutions using message queues or HTTP long-polling quickly lead to resiliency, scalability and development velocity challenges.
