AWS Networking DHCP and VPC

AWS Networking DHCP and VPC

AWS Networking DHCP and VPC

What is DHCP

DHCP servers dynamically assigns an IP address and other network configuration parameters to each device on a network so they can communicate with other IP networks
To get to DHCP in your VPC you ofcourse first click VPC in aws console
Click VPC

DHCP Options Set

You can set options in AWS for which address from the pool devices would get. So in AWS you can set the options such as DNS NTP NetBios servers - these are the options that devices would once they connect and get a new ip from your DHCP service this is called DHCP options set.

Click DHCP Option Set

DHCP option set is actually configuration params related to how to setup address protocol on the device that received the conf from DHCP not only how to get the ip get ip but you can also set other options.

Give DHCP option set a name

_

Give it a name

These are the options that new devices would get they would get the domain name the dns server ntp server etc.
  • Give the new dhcp option set a name.
  • Give it a domain name
  • Provide the dns server can do it later.
  • NetBIOS - do not need to set it.
Then just click create
And ! DHCP option set has been created

Subnets and DHCP Options Set

For each subnet you might need to create DHCP options.

Summary

For each subnet you might need to cretate dhcp options set. DHCP options set allow you to configure the options clients get when they connect and get a new IP such as domain name, ntp server name etc.
DHCP itself is used to provide dynamic addresses where required within your VPC

API Design Paper Summary and Review

API Design Paper Summary Introduction Is building API a solvable question, how far can we get into having good API’s and what is a good API at all? these are all very hard questions, usually you know the answers once you designed multiple APIs and got experience and then reviewed the decisions you have taken. Fortunately there are papers dealing with this problem exactly, for complex API’s used by a huge amount of people, the Qt API for example a very populate framework for desktop GUI building, and today we are going to go through a summary of that paper.

“The Little Manual of API Design” is a very nice paper written by Jasmin Blanchette has released a paper while working in trolltech, which is a Nokia company. I found it to be very clear and concise, and reassuring what we think of API design. It’s a difficult task that includes both artistic, social, programming and scientific skills. We are going to summarize this paper for you.

When you write an API you combine a set of symb…

Dev OnCall Patterns

IntroductionBeing On-Call is not easy. So does writing software. Being On-Call is not just a magic solution, anyone who has been On-Call can tell you that, it's a stressful, you could be woken up at the middle of the night, and be undress stress, there are way's to mitigate that. White having software developers as On-Calls has its benefits, in order to preserve the benefits you should take special measurements in order to mitigate the stress and lack of sleep missing work-life balance that comes along with it. Many software developers can tell you that even if they were not being contacted the thought of being available 24/7 had its toll on them. But on the contrary a software developer who is an On-Call's gains many insights into troubleshooting, responsibility and deeper understanding of the code that he and his peers wrote. Being an On-Call all has become a natural part of software development. Please note I do not call software development software engineering because …

Recursion Trees Primer

Recursion trees.

Controlling the fundamentals stands at the cornerstone of controlling a topic.  In our case in order to be a good developer its not enough or even not at all important to control the latest Java/JavaScript/big data technology but what's really important is the basics.  And the basics in computer science are maths, stats, algorithms and computer structure.

Steve wosniak the co-founder of apple said the same, what gave him his relative advantage was his deep understanding of programming and computer structure, this is what gave him the ability to create computer's which are less costly than the competitors (not that there were many) and by the way there were 3 founders to apple company one responsible for the technical side, one for the product and sales (Steve Jobs) and the third responsible for the company structure and growth, each of the three extremely important, it was not only the two Steve's but that's a topic for another episode.

And with that l…
