Make sense of edge computing vs. cloud computing

The internet of things is real, and itrsquo;s a real part of the cloud.

A key challenge is how you can get data processed from so many devices.

Cisco Systems predicts that cloud traffic is likely to rise nearly fourfold by 2020, increasing 3.9 zettabytes (ZB) per year in 2015 (the latest full year for which data is available) to 14.1ZB per year by 2020.As a result, we could have the cloud computing perfect storm from the growth of IoT.

After all, IoT is about processing device-generated data that is meaningful, and cloud computing is about using data from centralized computing and storage.

Growth rates of both can easily become unmanageable.[ Read the InfoWorld reviews: Amazon eases developers into IoT. | Azure brings IoT to .Net developers. | Stay up on cloud happenings with InfoWorld's Cloud Computing Report newsletter. ]So what do we do? The answer is something called “edge computing.” We already know that computing at the edge pushes most of the data processing out to the edge of the network, close to the source of the data.

Then itrsquo;s a matter of dividing the processing between the edge and the centralized system, meaning a public cloud such as Amazon Web Services, Google Cloud, or Microsoft Azure. To read this article in full or to leave a comment, please click here

How to keep multicloud complexity under control

“Multicloud” means that you use multiple public cloud providers, such as Google and Amazon Web Services, AWS and Microsoft, or all three—you get the idea.

Although this seems to provide the best flexibility, there are trade-offs to consider.The drawbacks I see at enterprise clients relate to added complexity.

Dealing with multiple cloud providers does give you a choice of storage and compute solutions, but you must still deal with two or more clouds, two or more companies, two or more security systems … basically, two or more ways of doing anything.
It quickly can get confusing.[ To the cloud! Real-world container migrations. | Dig into the the red-hot open source framework in InfoWorld’s beginner’s guide to Docker. ]For example, one client confused security systems and thus inadvertently left portions of its database open to attack.
It’s like locking the back door of your house but leaving the front door wide open.
In another case, storage was allocated on two clouds at once, when only one was needed.

The client did not find out until a very large bill arrived at the end of the month.To read this article in full or to leave a comment, please click here

Using Salesforce to access SAP? Pour yourself a stiff drink

The week after a U.K. court favored SAP in a $70 million licensing dispute, the software developer took another brewery to arbitration in the U.S., this time seeking damages of more than $600 million.The disputes—both are ongoing—bode ill for companies using platforms such as Salesforce.com to indirectly access data held in SAP systems subject to named-user licensing.“SAP investors may welcome this litigation, but it’s yet one more reason why new customers are fleeing to the hills, choosing Amazon Web Services or Google, where they can, for their future software needs,” said Robin Fry, legal director at software licensing consultancy Cerno Professional Services. “Why choose SAP if, despite being a loyal customer and careful attempts at compliance, there’s a real risk that they might bring a gun at your head or force you to restate your earnings down the line?”To read this article in full or to leave a comment, please click here

Serverless computing will drive out OpenStack private clouds

By now we all (should) know the benefits of serverless computing in the public cloud. InfoWorld’s Eric Knorr provides a good summary of serverless computing’s advantages, so I won’t go into the details here.What’s most interesting is that as Amazon Web Services, Google, and Microsoft get better and better, the private cloud providers are still moving at a snail’s pace.

The public cloud is where we see new technologies take off, such as machine learning, big data, and now serverless computing.

By contrast, the private cloud seems like the redheaded stepchild.To read this article in full or to leave a comment, please click here

Light a fire under Cassandra with Apache Ignite

Nikita Ivanov is co-founder and CTO of GridGain Systems. Apache Cassandra is a popular database for several reasons.

The open source, distributed, NoSQL database has no single point of failure, so it’s well suited for high-availability applications.
It supports multi-datacenter replication, allowing organizations to achieve greater resiliency by, for example, storing data across multiple Amazon Web Services availability zones.
It also offers massive and linear scalability, so any number of nodes can easily be added to any Cassandra cluster in any datacenter.

For these reasons, companies such as Netflix, eBay, Expedia, and several others have been using Cassandra for key parts of their businesses for many years.To read this article in full or to leave a comment, please click here

What’s behind VMware’s Wavefront acquisition?

VMware’s acquisition of monitoring software maker Wavefront for an undisclosed sum is a move core to VMware's strategy to round out its portfolio for facilitating and managing hybrid cloud environments.
It highlights in the need to ensure that applications running between private and public clouds perform up to par.Companies undertaking digital transformations are leaning heavily on hybrid clouds to deploy software, a scenario playing out across nearly every industry.

To enable this at a high velocity, companies are instituting DevOps, in which code is constantly written, shipped, run and regularly refined.
In DevOps environments, corporate developers code application functionality, called microservices, which they ship via virtual containers to run between private cloud environments and public cloud systems such as Amazon Web Services, Microsoft Azure and Google Cloud.To read this article in full or to leave a comment, please click here

Fortinet upgrades for better cloud, SD-WAN protection

Fortinet has rolled out a new version of its FortiOS operating system that gives customers the ability to manage security capabilities across their cloud assets and software-defined wide area networking (SD-WAN) environments.With FortiOS 5.6, the company’s Fortinet Security Fabric gives a view of customers’ public and private clouds – including Amazon Web Services and Azure – as well as assets on and their software-defined WANs, says John Maddison, Fortinet’s senior vice president of products.[ Docker, Amazon, TensorFlow, Windows 10, and more: See InfoWorld's 2017 Technology of the Year Award winners. | Cut to the key news in technology trends and IT breakthroughs with the InfoWorld Daily newsletter, our summary of the top tech happenings. ]+More on Network World: DARPA to eliminate “patch & pray” by baking chips with cybersecurity fortification+To read this article in full or to leave a comment, please click here

AWS is moving beyond IaaS and PaaS

Last week, Amazon Web Services launched Amazon Connect, a cloud-based contact center service.

The objective is to provide enterprises with an easier-to-use and faster-to-deploy call center system.

But there’s deeper meaning to Amazon Connect than simply a new service from AWS.From a technology perspective, Amazon Connect works the same way as Amazon's customer service system, incorporating its Lex AI technology for natural language processing, which is also used by the Alexa virtual assistant—yes, Alexa from the Amazon Echo.To read this article in full or to leave a comment, please click here
