Microsoft details post-LinkedIn plans to EU

Antitrust regulators at the European Union like to make American firms jump through an awful lot of hoops before approving a big merger, as they did to Oracle when it spent nine months trying to acquire Sun Microsystems back in 2009. Now they are doing it to Microsoft over its proposed $26.2 billion acquisition of LinkedIn. Earlier this month, regulators expressed concerns to Microsoft that it would stifle access to LinkedIn's APIs and other mobile concerns. Last week, the European Commission said Microsoft had responded to those concerns by proposing "concessions," which Reuters has obtained. According to the news outlet, Microsoft has made three major promises to the European Commission:To read this article in full or to leave a comment, please click here

7 simple truths you should know about the hybrid cloud

I'm about to tell you something that may shatter what you think about the cloud: The hybrid cloud does not exist.The enterprise cloud adoption manual puts hybrid cloud at the top of the list.

Security budgets continue to grow, but is it enough?

Cybersecurity is an increasing concern in the enterprise as the number of high-profile breaches reported only grow each year. In 2015, there were a reported 781 data breaches in the U.S., making it the second highest year for security threats, according to data from the ISACA. And 40 percent of those data breaches happened in the business sector.So it's no surprise that Business Insider Intelligence reports an estimated $655 billion will be invested in cybersecurity initiatives between 2015 and 2020. However, in 2015, worldwide cybersecurity spending reached only $75.4 billion, according to Gartner, jumping to an estimated $2.77 trillion in 2016. Those numbers suggest that businesses are only just catching on to the importance of cybersecurity in the workplace, but are they too late?To read this article in full or to leave a comment, please click here

Retailers get an IoT wake-up call

The DDoS attack against Dyn on Oct. 21 may not have been anything new or sophisticated to those steeped in cybersecurity, but it should serve as a significant wake-up call to retailers this holiday season and beyond, say experts. The hack — which led to vast consumer trouble loading major websites such as Etsy, AirBnB, Netflix and Twitter — was particularly notable because it appears to have relied on infecting internet of things (IoT) devices such as cameras, monitors and routers with software meant to flood targets with overwhelming traffic.[ Related: DDoS attack shows dangers of IoT 'running rampant' ]To read this article in full or to leave a comment, please click here

HPACK: the silent killer (feature) of HTTP/2

If you have experienced HTTP/2 for yourself, you are probably aware of the visible performance gains possible with HTTP/2 due to features like stream multiplexing, explicit stream dependencies, and Server Push.

There is however one important feature that is not obvious to the eye. This is the HPACK header compression. Current implementations of Apache and nginx servers, as well edge networks and CDNs using them, do not support the full HPACK implementation. We have, however, implemented the full HPACK in nginx, and upstreamed the part that performs Huffman encoding.

This blog post gives an overview of the reasons for the development of HPACK, and the hidden bandwidth and latency benefits it brings.

Some Background

As you probably know, a regular HTTPS connection is in fact an overlay of several connections in the multi-layer model. The most basic connection you usually care about is the TCP connection (the transport layer), on top of that you have the TLS connection (mix of transport/application layers), and finally the HTTP connection (application layer).

In the the days of yore, HTTP compression was performed in the TLS layer, using gzip. Both headers and body were compressed indiscriminately, Continue reading
