Apps are Key Enablers
Making information
more broadly available
Capturing and refining competitive
and innovative processes
Gather input and interaction
from broader constituents
Improved accessibility =
faster decision making
Automation for
consistency and speed
Improved customer service

Challenges
• Responsive vs. Adaptive vs. RESS (Responsive + Server
Side)?
– Server side or client side?
– Single URL or different URLs?
• Graphics Design
– Can require significant work & time
– Different skills: good graphics designers are scarce,
expensive

Ideally, build once.
Smart, auto-responsiveness.

Decoupled UI Components.
Professional Template starting points.

Caution: Avoid lock-in and dead-end functionality.
Ensure: Open Standards and Extensibility.

Trend: APIs

Growth of APIs
Source : programmableweb
As of today, the number
of registered APIs on
ProgrammableWeb has
crossed 13000 APIs.

Why is API a trend?
• Increase in consumption of
data/functionality from multiple
devices.
• Need for easy, usable, secure and
loosely standardized contracts

What is API?
• Application Programming Interface
• Way to expose data/functionality
– Operation, Input, Output and Types
• Not new
• SOA with SOAP/WSDL, REST services

Modern APIs need to
• Be usable
• Optimize network traffic.
• Be simple to understand
• Provide finer resource level control.
• Be secure

RESTful APIs meet modern needs
Fine Grained
Access
• /v1/customers/[customer-id]
Simple to
Understand
• CRUD operations map to HTTP method
POST/GET/PUT/DELETE
Usable and
Optimized
• JSON Response format is optimized as well
as understandable.
Be Secure
• OAuth2.0 for finer grained security

Challenges implementing APIs
• Everything needs a representation / API
– Software services / data
– Things being connected with IoT (Internet of Things)
• Every “Thing” needs a representation / APIs to get connected in the
ecosystem of IoT
• API Consumption still requires a lot of technology
knowledge / investment.
• API should provide secure access.

API Driven Development
• API can no more be an
afterthought
• API should be
created/updated for every
entity in the application,
preferably automatically
API Driven development
with easy testing of
generated/created APIs.

Simplified API Consumption
Pre-fabricated application
components providing the
API usage can boost
developer productivity
tremendously.

Control API Access
API Access Configuration
• Not exposed at all
• Only for same application
• Internally in organization
• Public APIs

Trend: Continuous
Delivery

Continuous Delivery trend

Application
Process having a
steady gain and
being adopted
more and more in
past few years.

Continuous Delivery – Why?
• Move from software to SaaS means getting updates
released is now only restricted by your own
operations.
• More number of releases, ensure truly agile process
• React quickly and respond to change

Challenges with Continuous Delivery

What is Docker?
Build, Ship, and Run
Any App, Anywhere
VM Container
Each application in a VM
consist of Guest OS,
making a few MB
application 10s of GB
application.
Isolated process in same
Host OS, lightweight and
hence much more
portable and efficient.
How is it
different from
VM?

• Lots of technologies to assemble
• Moving workloads to Docker
• Managing software stacks & configurations
• Automating deployment processes
• Migration of Data
• Orchestration of containers including
– Scheduling and placement of containers
– Cluster Management
– Inter-container Communications
– Network configuration
– Discovery of services
Challenges of Implementing Docker

Enterprise IT also needs
• Role Based Access Control
• Snapshots, backup and recovery of data
• Monitoring of infrastructure, containers and
workloads
• Easy and fine grained upgrades
• Optimized Resource Utilization
• Fault Tolerant Application
• Scalability as needed
• Uncompromised Security

Docker Accelerator
• Simplify implementation
• Meet enterprise IT’s unique needs
• Maximize the value of Docker

Dockerize Workload: Docker Images
Upload

Provide Commands to
1. Install Software
2. One time

3. Startup scripts
Configurations required
1. Ports to be opened
2. Environment

A r c h i t e c t
D e v O p s
Configures “App Stack” by
configuring one or more services.
Easily configures connections
amongst services by specifying
environment variables, ports etc..
C o n f i g u r e d S e r v i c e s
1. Functional decomposition –
Easier operations, upgrades
and separation of stack
2. Horizontal Scaling – scale
individual services by adding
more capacity and without re-
architecting
3. Isolation & data partitioning –
fault isolation and partition
data based on tenant
Micro Services architecture -
Application is composed of
multiple smaller micro services.

Trend: Microservices

Microservices
Source: Google Trends
Steep rise in recognition
of Microservice
Architecture from 2014

Microservices further boosted by
• Availability of APIs for communications enables loosely
coupled components
• Continuous Delivery enables better release
management of multiple services / applications

Monolithic Traditional Architecture
Source: microservices.io
Source
Shortcomings
• Updates and upgrades are difficult
• One component update breaks another component
• Less number of releases
• Delayed releases
• Unable to get truly agile

Microservice Architecture
Source: microservices.io Source
Advantages
• Modular application
• Easy maintenance, updates for application
• More releases and agile processes
• Independently scalable

Challenges Implementing Microservices
• Architecting multiple smaller services / applications
– With Microservices, services become synonymous to
application.
• How to make services available for other applications?
– Multiple small services/application require a sophisticated
system for communication.
• Technical cost to consume APIs
– Consuming APIs should be a piece of cake to realize value of
microservices

It should be easy to publish and share APIs with other developers
in the enterprise.

Aligning to Trends

Challenges in aligning to these Trends
• Requires a lot of research
• Initial setup is complicated
• The setup takes time to mature
• Configuration and setup of individual MSA
components need to evolve
• Lots of boilerplate code
• Release management becomes nightmare

RAD  new RAADD
Rapid API Application Development & Deployment
• Automatic Responsive Modern UI
• Easy for non-UI developers. Flexible for pro
developers.
• API Driven Development with Micro Service
Architecture
• Continuous Delivery leveraging Docker
– Simplify setup and management of Docker and all other
requisite technologies.
– Maximize value from Docker

RAADD Cautions
• Open Technologies?
• Open Source?
• Extensible?
• Vendor-Lockin (e.g., proprietary runtime)?
• Delivery Options (On-Prem, SaaS)?

What if RAADD Platform provides
these benefits too?
