If we assume economies of scale, eventually, it may become silly for a business to own lots of IT infrastructure. Why not lease it from cloud providers? They’ll be able to do it cheaper, and besides…they’re experts. I think it’s possible that businesses will eventually migrate most (if not all) of their applications to the cloud.
The connection between your office and the central office is what we call the last mile. The last mile, at least in the US, has one big problem: it’s often owned by a single organization.
My interpretation of the SD-WAN value prop can be boiled down to cost savings, simplified operations, and improved application performance over inconsistently performing WAN links. Here’s the conundrum. An engineer might instinctively recoil at this sort of value proposition.
Juniper flexed its muscles at the Innovation Showcase held in March 2015. What did they talk about? What does it mean for their customers going forward? I perform an introductory analysis.
Should you go from the CCNA to the CCIE directly? Why or why not? Considering SDN, is going after the CCIE even a good idea? I opine.
During a bout of stress & jet lag induced insomnia, I logged onto Twitter in the wee hours to see what folks were saying. I found a number of twitpisses in my timeline. Twitpisses are arguments in which people assert that Someone On The Internet Is Wrong in 140 characters or less. After said assertion, […]
I’ve seen a list entitled “Why Talented Employees Stay” floating around Twitter. The list has been bothering me, because I don’t think it’s quite…right. The list is interesting, but I don’t believe it tells the whole story. Taken at face value, I think the list could even make it more difficult to retain certain people — not less.
Throughput Throughput is the rate at which data is traversing a link. For example, take a look at the virtual router output below. The throughput rate is 643Kbps in each direction.
CSR1KV01#show interface gi1 | include rate
30 second input rate 643000 bits/sec, 58 packets/sec
30 second output rate 643000 bits/sec, 58 packets/sec
Goodput Goodput is the rate at which useful data traverses a link. Assuming an uncongested path between endpoints, goodput and throughput will be as […]
GoDaddy recently entered the turnkey WordPress hosting fray, offering a one year trial for $1 a month. I had been toying with the idea of another blog, so I decided to give them a try. The experience of hosting at GoDaddy has been…sort of neutral.
I will be at Interop Las Vegas this year from Tuesday, April 28 through Thursday, April 30. If you are a vendor who would like to brief me, someone who would like to explore consulting opportunities, or if you just want a word, let’s connect. I’d be happy to swing by your booth, meet for coffee, or simply hang out.
This week, Greg and I decided to do a review of some of the briefings we received via an audio recording. We published the audio on the Packet Pushers Community Show feed, which you can subscribe to specifically on iTunes or access via the Packet Pushers Fat Pipe iTunes feed. Here’s a summary of my take on these briefings.
There’s a lot to SD-WAN technology, and there are a number of devils in the implementation details that have been nagging at me as I listen to briefings and record podcasts from vendors in the space. SD-WAN technology questions that bother me… What’s the impact to hosts on virtual machine based endpoints, i.e. how much CPU does an SD-WAN […]
I had a need this past weekend to migrate from one old Mac running OS X Yosemite to another old Mac, also running OS X Yosemite. Apple’s Migration Assistant can get this done, but I was looking to zero out the target Mac first. You can google a few different ways to do this, but […]
