Basic Step-Functions Input and Output and Lambda— Passing Data From one to another
With so much focus on serverless in Re-Invent 2022 and the advantages of Step Functions, I have started to transform some of my code from Lambda to Step Functions.
Step-Function was hard until I figured out how data values can be mapped for input and how data can be passed and transformed between Lambda functions. I have made a small attempt for someone who is starting in step functions for understanding the various steps involved.
Basically, Step Functions can be used to construct business logic and Lambda can be used to transform the data instead of transporting with Lambda-Invokes from Lambda Functions.
Let’s take the following example
I have step_function_1 which has the requirement to invoke another lambda if my_var is 1 else do not do anything.
This is a simple if-else logic followed by the lambda-invoke function
Now, the power of step-functions will come into play to write these conditional and also pass data from Lambda to Other making it super scalable for editing in future and all of the code will seem very logical and pictorial, best part is this can be designed instead of learning Amazon’s State Language.

Asking Meaningful Questions: How To Break Negative Patterns
Unconscious patterns of behavior can impede our professional progress. For example, you might watch others capitalize on ideas you have but don’t act on. Or your abrupt delivery of “the facts” alienates your colleagues and creates friction that can be detrimental. As I’ve recognized patterns in my own life and career, I’ve developed ways to […]

Why the Industry Needs SASE Standards
MEF recently published the industry’s first standard for SASE, which defines common terminology, attributes of the service, and a service framework, along with a Zero Trust frameworkAzure Host-Based SDN: Part 1 – VFP Introduction
Azure Virtual Filtering Platform (VFP) is Microsoft’s cloud-scale virtual switch operating as a virtual forwarding extension within a Hyper-V basic vSwitch. Figure 1-1 illustrates an overview of VFP building blocks and relationships with basic vSwitch. Let’s start the examination from the VM vm-nwkt-1 perspective. Its vNIC vm-cafe154 has a synthetic interface eth0 using a NetVSC driver (Network Virtual Service Client). The Hyper-V vSwitch on the Parent Partition is a Network Virtual Service Provider (NetVSP) with VM-facing vPorts. Vm-cafe154 is connected to vPort4 over the logical inter-partition communication channel VMBus. VFP sits in the data path between VM-facing vPorts and default vPort associated with physical NIC. VFP uses port-specific Layers for filtering traffic to and from VMs. A VFP Layer is a Match Action Table (MAT) having a set of policy Rules. Rules consist of Conditions and Actions and are divided into Groups. Each layer is programmed by independent, centralized Controllers without cross-controller dependencies.
Let’s take a concrete example of Layer/Group/Rule object relationship and management by examining the Network Security Group (NSG) in the ACL Layer. Each NSG has a default group for Infrastructure rules, which allows Intra-VNet traffic, outbound Internet connection, and load balancer communication (health check, etc.). We Continue reading

Friends Hard to Find These Days? These Surprising Insights May Help
Finding true friends who we can trust in life is becoming increasingly more difficult with the advent of technology and its ability to create distance between people. We may think that having a large circle of acquaintances is great, but this does not equate to having real friends. There are many reasons for this phenomenon, such as being overly connected in the digital world versus taking time away from our screens to interact face-to-face with those around us. But, there is surprisingly some insight into the current climate that may help foster meaningful connections and relationships that last. Here are some of the surprising insights that may help you find true friends in today’s world:
Start with yourself
If you want to make meaningful connections and develop real friendships, it is important to start by looking inward. Investing in your own emotional well-being and self-confidence will ensure that you are comfortable interacting with others on a deeper level. Taking time to reflect on your own identity, what you need from friends and how you can be a good friend will make all the difference in your ability to form lasting relationships.

Lambda — Sync / Async Invocations
< MEDIUM: https://medium.com/@raaki-88/lambda-sync-async-invocations-29e12a47ce85 >
A short note on Lambda Sync and Async Invocations. After Reinvent 2022, most of us started to think around Event-Driven architectures, especially using Event-Bridge, and Step-Functions at the core of state changes and function data pass.
I like these ideas very much. For me, before step-functions and event-bridge Lambda had this beautiful feature of Event/Request-Response knobs which served the purpose. With Step-Functions in place, you remove the complexity of maintaining state and time-delay logic and connectivity to different AWS services without relying on BOTO3 API connectivity. As one of the talks in Reinvent 2022 iterated that Lambda should be used to transform the data but not transfer the data.

This is by far the best video that I have seen around the topic, this guy has nailed it to perfection! Please watch it if you are interested in these architectures.
For those who were looking out for using Lambda Request-Response/Event-based invocations few things that I have not seen anyone else write about some nitty gritty details
Let’s say
def call_other_lambda(lambda_payload):
lambda_client = boto3.client('lambda')
lambda_client.invoke(FunctionName='function_2',
InvocationType='Event', Payload=lambda_payload)
def lambda_handler(event, context):
print(event.keys())
get_euiid = event['end_device_ids']['device_id']
lambda_payload = json.dumps( {json. Continue reading

Do I Need to Automate SONiC? How Can I Do It?
SONiC, which stands for Software for Open Networking in the Cloud, is a Network Operating System (NOS). SONiC’s main purpose is to run on the data center switches and provide simple and reliable connectivity between endpoints (Baremetal servers, virtual machines, containers, etc). As it is a piece of the network software, which runs on network hardware, it is for sure requires automation.
The good news is that it supports RESTCONF and GNMI with OpenConfig YANG modules, which we extensively cover in our Network Automation Trainings:

SCP not working with MacOS 13 Ventura?
You have updated your MacOS to version 13 (Ventura) and a simple SCP to a network device does not work anymore? In fact, this is normal, here is the reason and how to solve this. The symptom The SCP command that you have already done thousands of times to upload or download a file from/to a network device gives an error, for example: ~ scp nxos64-cs.10.2.4.M.bin admin@myswitch:bootflash:/// (admin@myswitch) Password: subsystem request failed on channel 0 scp: Connection closed The reason The SCP protocol has been deprecated in OpenSSH 9.0 which…

Making It Work in 2023
We’re back to the first of the year once again. January 1, 2023 is a Sunday which feels somewhat subdued. That stands in contrast to the rest of the year that felt like a rollercoaster always one heartbeat away from careening out of control. As is the tradition, I’ll look at the things I wanted to spend more time working on in 2022:
- More Analytical Content: I have to honestly give myself a no on this one, at least from a technical perspective. I did spend some time making analytical content for my Tomversations series. However, the real difference in analytical content came from my posts about leadership and more “soft skill” focused ideas. I’ve gotten more comments about those posts than anything in 2022 and I couldn’t be more proud.
- Saying No to More Things: This is the part where I would insert an animated GIF of someone laughing manically. While I did make strides in telling people that I have way too much going on to take care of one extra thing the reality is that I took on more things that I probably should have. That’s something that I definitely do need to change but the real Continue reading

2022 Working Environment
The change of the year is always a good time to reflect. This year I’ve made major changes in my physical environment by reshaping many of the things about this house we recently moved to in Knoxville. Besides ripping out the entire kitchen, replacing all the floors, and reworking the fireplace, it was a good chance to rethink the office I work in every day. I’m rather persnickety about the lighting, layout, and tools I use (although a lot of people still think I’m crazy for using fairly standard tools, like Word, for writing).
This is my space, pretty much—
I use an adjustable height desk where I’m either leaning or standing—if I want to sit to read something, I normally grab a tablet and sit in the red chair off to the side, or even go someplace else in the house. I prefer not to read on my main computer screen most of the time. I normally keep ambient light to a minimum, and turn my monitor brightness down to pretty minimal, as well—below 20%.
I’m currently running an LG 38in curved monitor. I don’t game, so I care a lot more about resolution than refresh rate, etc. My Continue reading
