Performance Implications of CNAME Chains vs Oracle ALIAS Record

The CNAME resource record was defined in RFC 1035 as “the canonical name for an alias.” It plays the role of a pointer, for example, the CNAME informs the requestor that www.containercult.com is really this other name, instance001.couldbalancer.example.com.

The CNAME record provides a “configure once” point of integration for third party platforms and services. A CNAME is often used as opposed to an A/AAAA record for the same reason developers often use variables in their code as opposed to hard coded values. The CNAME can easily be redefined by the third party or service provider without requiring the end user to make any changes.

A stipulation that prevents use of the CNAME at the apex is that no other records can exist at or alongside a CNAME. This specification is what prevents an end user from being able to place a CNAME at the apex of their zone due to the other records, which must be defined at the apex such as the Start of Authority (SOA).

ALIAS / ANAME – The way of the future 

The Oracle ALIAS record allows for CNAME-like functionality at the apex of a zone. The Oracle implementation of the Continue reading

Study: Use of IoT in corporate networks is soaring

We’ve reached the sharp part of the adoption curve for IoT, as a recent study shows skyrocketing adoption of the technology across all business sectors for a huge range of different purposes.Vodafone’s annual IoT barometer this month found that 84% of the 1,278 senior IT decision-makers who responded had increased their adoption and use of IoT solutions in the past year. 12% of the respondents had at least 10,000 connected devices in use at their company, while 6% had more than 50,000 in operation.+ALSO ON NETWORK WORLD: Forrester: 3 ways IoT can drive business value + FAQ: What is NB-IoT?To read this article in full or to leave a comment, please click here

IDG Contributor Network: How smart cities can protect against IoT security threats

Smart cities, which were once confined to the realms of science fiction books, are rapidly becoming a reality all around the globe. Unfortunately, like all revolutionizing innovations, smart cities are developing their own unique challenges alongside of their perks. So what are industry insiders and tomorrow’s city planners doing to face these challenges?The security issues facing smart cities are unlike anything ever before seen, and solutions to these problems haven’t yet sprung up en masse, meaning many different interest groups have proposed their own respective plans. By combing through some of today’s proposed solutions, we can identify some of the leading trends that will come to dominate the future of smart city security.To read this article in full or to leave a comment, please click here

BrandPost: Network-as-a-Service, Not a Barrier

Enterprises are getting hooked on “everything-as-a-service” and the revolution that ripped through the data center is rapidly encompassing network infrastructure. As more and more IT assets rely on cloud computing, IT decision makers need to make sure their networks aren’t becoming obstacles to achieving business objectives.According to the State of the CIO Survey 2017, “IT investments are being directed toward business initiatives such as improving customer experience (40%), transforming existing business processes (40%), increasing operational efficiency (35%), and growing the business (33%).”To read this article in full or to leave a comment, please click here

SDN: Is Here to Stay

In an October 3, 2017 article published in Network Computing, titled: “SDN: Time to Move On,” Gartner Analysts report on the state of software-defined networking and advise enterprises to shift their focus. It has triggered some interesting conversation in the SDN field. As a leading player of SDN technology, we have received several inquiries for comments on the article. While the controversial title grabbed a lot of attention, it’s alarming to many and far from reality. More importantly, it differs from what Gartner reports have concluded.

From what we see in the market, SDN has already landed real use cases and built the momentum to change the production network. However, as Gartner expressed in the reports, we have seen two gaps in adopting SDN: It takes a long time for customers to adopt this nascent technology; and while SDN can be used to solve many imminent issues, it is not a panacea to all networking problems.

image-profit_imageshutterstockAccording to Gartner, “SDN started as a new technical architecture, but brought into light some valuable concepts that outlived the original blueprint,” Gartner VP Distinguished Analyst, Joe Skorupa and Research Director, Danilo Ciscato wrote. The article also reveals, “The story’s different in Continue reading

Choosing your chassis: a look at different models

Simplicity, scalability, efficiency, flexibility — who doesn’t want to be able to use those words when talking about their data center? As more and more companies adopt web-scale networking and watch their growth rapidly increase, the need for an equally scalable and powerful solution becomes apparent. Fortunately, Cumulus Networks has a solution. We believe in listening to what our customers want and providing them with what they need; that’s why we supports the Facebook Backpack for 64 to 128 ports of 100gig connectivity and the Edge-Core OMP800 for 256 ports of 100gig connectivity. So, what exactly is so great about these chassis? Let’s take a closer, more technical look.

The topology

When designing and building out new data centers, customers have universally agreed on spine and leaf networks as the way to go. Easy scale out by adding more leafs when server racks are added and more manageable oversubscription by adding more spines makes this design an obvious choice. We at Cumulus have built some of the largest data centers in the world out of one-rack-unit switches: 48 port leafs and 32 port spines. These web-scale data centers build “three-tier” spine and leaf networks using spine and leaf “pods” Continue reading

Oracle leverages machine learning to manage, secure enterprise systems

Oracle is not the first company that comes to mind when you think of enterprise security, but the company announced at its recent OpenWorld conference new products with artificial intelligence (AI) and machine learning capabilities to quickly identify security threats.The company introduced two new sets of integrated suites called Oracle Identity Security Operations Center (SOC) and Oracle Management Cloud. It claims they will help enterprises forecast, reduce, detect and resolve cybersecurity threats in minutes rather than days and assist remediation of application and infrastructure performance issues.It makes sense for Oracle to jump into this field even if it is full of established players like Symantec, Sophos, Tripwire and far more. Since Oracle’s databases are often a target of hacker attacks, who better to secure an Oracle database than Oracle? To read this article in full or to leave a comment, please click here
