Comparison: Cisco Catalyst 9500 Vs Cisco Catalyst 4500 Vs Cisco 3850 Switches

Today I am going to talk about the fixed core chassis Cisco catalyst 9500 which Cisco released a month back. Cisco 9500 is actually enhanced version of Cisco catalyst 4500 chassis and also Cisco 3850 Switch. There are lot of other best features in Cisco 9500 Chassis as some of the features are just amazing in this device.

So we have Cisco 3850, Cisco 4500 Catalyst Switches, Cisco 6500 Catalyst switches, Cisco 6800 Catalyst switches and now Cisco 9000 catalyst switches with 3 flavours ( Cisco 9300 catalyst switches, Cisco 9400 catalyst switches and Cisco 9500 Catalyst switches)

How topology and the demand changes, below is the example topology showing the changes which leads to the next generation fabric network with cloud ready solutions and automation. CLI is gone for the campus fabric, All policy is driven with the SDN controller.

Fig 1.1- Network topology and Next Generations

If we have Cisco 4500 and Cisco 3850 fixed chassis why we required Cisco 9500 chassis ?
I knew this is one of the question which you actually thinking and for this i would like to say that you need to understand the next generation campus requirements where customer wants to be Continue reading

Searching for ground truth in IoT

I’ve been reading and writing daily about the Internet of Things (IoT) for about a month, and I have not found ground truth. I’m not new to the field, but now focused on IoT I am trying to find a relative measure of the importance of IoT developments.One of the definitions of ground truth in the Oxford Dictionary is: “Information obtained by direct observation of a real system, as opposed to a model or simulation; a set of data that is considered to be accurate and reliable, and is used to calibrate a model, algorithm, procedure, etc.” Calibrating the development of the IoT with ground truths that match the 20 billion to 50 billion forecasted devices requires a departure into the leap-of-faith lane. This is not pessimism, but a lack of published information that probably does not exist outside of research papers.   To read this article in full or to leave a comment, please click here

Hit Pause: Take a Moment to Reflect on the Repercussions of the Recent Ransomware Attacks

As these devastating global ransomware attacks illustrate, cybersecurity is not an issue that can be ignored. Any time a device or system is connected to the Internet, it is a potential target. What was once just another lucrative means of extorting money from Internet users, ransomware is emerging as a preferred tool for causing widespread disruption of vital services such as hospitals, banks, shipping, or airports. Attacks are growing more sophisticated and more enduring, with longer term damaging effects and wider impact. Ransomware exploits the slow pace of security patching, systems that are dependent on old software, and poor backup practices.

Microsoft rumor: Company to reorganize cloud computing division

Multiple news outlets in Seattle and the tech press report that Microsoft plans to announce a significant reorganization in an effort to refocus its cloud computing division. In the process, a lot of people are going to lose their jobs.The Seattle Times, Puget Sound Business Journal, Bloomberg and TechCrunch all cite sources claiming that the news could come this week, and that could mean layoffs in the thousands. RELATED: How a giant like GE found a home in the cloud The Seattle Times said it was unclear what groups would be affected and where they are located but that the move would be to get its sales teams to emphasize its cloud computing products instead of pushing packaged software. To read this article in full or to leave a comment, please click here

BrandPost: Key SD-WAN Solution Evaluation Criteria

On June 3, 2017, Andrew Lerner, vice president of research for enterprise networking at Gartner published a new blog: SD-WAN is going Mainstream. In this blog, Andrew offered two key takeaways:1.  SD-WAN is real and has real and tangible benefits.2.  At the same time, SD-WAN has downsides and/or challenges affiliated with early deployments. The downsides are mainly around gaps many vendors have for features like IPv6, WAN optimization, etc.I agree with Andrew’s assessment that there are downsides to many offerings, and want to underscore the key considerations for distributed enterprise when selecting the right SD-WAN solution. It’s reflective of carefully listening, learning and adapting to our more than 400 production customers around the world who evaluated multiple SD-WAN solutions before selecting Silver Peak Unity EdgeConnect.To read this article in full or to leave a comment, please click here

Worth Reading: Hijacking Bitcoin

It turns out that if you can hijack less than a hundred BGP prefixes (feasible) you can isolate about 50% of the mining power in the network. Once a collection of nodes are partitioned from the network the network becomes more vulnerable to double spending attacks, transaction filtering, and selfish mining attacks. —Morning Paper

IDG Contributor Network: Fraud and the Internet of Things

During the past few years, the Internet of Things (IoT) has become one of the hottest movements of our time. Although many technology trends and buzzwords come and go overnight, it’s clear that the IoT is here to stay. Almost half of the world's population is online, and technology is a deeply integrated part of our lives. Smart thermostats regulate our business and household temperatures, connected cameras watch over our homes and pets, online TVs and speakers respond to our every need, and intelligent devices constantly monitor our health.According to Gartner, the number of world-wide Internet connected devices will grow to 11.4 billion by 2018. It’s a phenomenal trend that will continue to spread until human and machine connectivity becomes ubiquitous and unavoidably present.To read this article in full or to leave a comment, please click here

How to make your site HTTPS-only

How to make your site HTTPS-only

The Internet is getting more secure every day as people enable HTTPS, the secure version of HTTP, on their sites and services. Last year, Mozilla reported that the percentage of requests made by Firefox using encrypted HTTPS passed 50% for the first time. HTTPS has numerous benefits that are not available over unencrypted HTTP, including improved performance with HTTP/2, SEO benefits for search engines like Google and the reassuring lock icon in the address bar.

How to make your site HTTPS-only

So how do you add HTTPS to your site or service? That’s simple, Cloudflare offers free and automatic HTTPS support for all customers with no configuration. Sign up for any plan and Cloudflare will issue an SSL certificate for you and serve your site over HTTPS.

HTTPS-only

Enabling HTTPS does not mean that all visitors are protected. If a visitor types your website’s name into the address bar of a browser or follows an HTTP link, it will bring them to the insecure HTTP version of your website. In order to make your site HTTPS-only, you need to redirect visitors from the HTTP to the HTTPS version of your site.

Going HTTPS-only should be as easy as a click of a button, so we Continue reading
