" A serverless architecture is a way to build and run applications and services without having to manage infrastructure. Your application still runs on servers, but all the server management is done by any cloud provider. In this model, the cloud provider is responsible for managing and scaling the servers for the customer, allowing for increased scalability and cost savings. Functions-as-a-Service (FaaS) platforms, such as AWS Lambda and Google Cloud Functions, are commonly used to build serverless applications."

Serverless Architecture

2. Lack of etiquette and manners is a huge turn off.
KnolX Etiquettes
Punctuality
Join the session 5 minutes priorto
the session start time. We start on
time andconclude on time!
Feedback
Makesure to submita constructive
feedback for all sessions as it is
very helpful for the presenter.
Silent Mode
Keep yourmobiledevices in silent
mode, feel free to moveout of
session in case you need to attend
an urgent call.
Avoid Disturbance
Avoidunwantedchitchat during
the session.

4. What is Serverless
No on-servers' components!!!
Infrastructure As A Service –
e.g Azure Files, Storage Accounts,
Compute Storage
PlatformAs a Service – e.g Azure SQL DB,
Amazon RDS, GCP Big Query
Software As a Service – Email, Trello,
Office 365
Iaas Vs Paas Vs Saas
Back-End As a Service - fully incorporate
third-party, cloud-hosted applications and
services, to manage server-side logic and
state.
Functions As a Service
logic written by a developer, and it run's in
stateless compute containers that are
event-triggered, or may only last for one
invocation, and fully managed by a third
party
Baas And Faas
The term “Serverless” is confusing as it
contains both -
server hardware and server processes
But
running somewhere and are taken care
by someone else other than the
organization building the serverless
application.

7. Key Points to Consider
Faas
Design
No language Barrier
Deploy
upload the code to provider
Optimize
Horizontal Scaling !! No worries
Monitor
Fully Manged Services
Model
No Server Management

8. Key Points to Consider
Faas functions
State - Less
a FaaS function that is
required to be persistent
needs to be externalized
outside of the FaaS
function instance.
Duration
Timeouts, eg For AWS
Lambda – 5 min
Start-Up Time
Cold Start or Hot Start

Security Concerns
No server side protection, IAM
polices, vendor specifc security
measure
No In Server State
No In mem or cache
Multitenancy
problems
One Machine- Multi Tenants
Vendor control
Mass Vendors in the market
