في الفيديوهات دي بيتم توضيح بعض التطورات اللي حصلت في صناعة البرمجيات من حيث ال Software Life Cycle و ال Architecture الجديد زي ال Micro-services و طرق تخزين البيانات الجديدة و طرق ال Deployment الجديدة وكمان المهام الذكية اللي بقت بتطلب من الSoftware. يمكنكم متابعة مقالاتي التقنية على الرابط التالي http://galaldev.blogspot.com.eg/ ويمكنكم متابعتي على Facebook على الرابط التالي https://www.facebook.com/galaldev رابط فيديو المحاضرة https://www.youtube.com/playlist?list=PLLFqEKhpE3ZVDzWCiJzmfiBmeB-ZnaAyX

1. The Modern
Software
Simple Introduction for the modern software development
and deployment
By Mohamed Galal

2. Outline
In Life Cycle
In Architecture
In Data Storage
In Deployment
In Software Task

3. In Life Cycle
Systems built using Agile
Agile template Scrum , Kanban … etc.
Software development splits into small stages
, iterations , sprints
Project splits on dependent small teams
DevOps

4. In Architecture
The most modern software architecture is Microservices

5. More about Microservices
In a microservices architecture, services are small, independent, and loosely coupled.
Each service is a separate codebase, which can be managed by a small development team.
Services can be deployed independently. A team can update an existing service without
rebuilding and redeploying the entire application.
Services are responsible for persisting their own data or external state. This differs from the
traditional model, where a separate data layer handles data persistence.
Services communicate with each other by using well-defined APIs. Internal implementation
details of each service are hidden from other services.
Services don't need to share the same technology stack, libraries, or frameworks.

6. Microservices Components
Management. The management component is responsible for placing services on nodes,
identifying failures, rebalancing services across nodes, and so forth.
Service Discovery. Maintains a list of services and which nodes they are located on. Enables
service lookup to find the endpoint for a service.
API Gateway. The API gateway is the entry point for clients. Clients don't call services directly.
Instead, they call the API gateway, which forwards the call to the appropriate services on the
back end. The API gateway might aggregate the responses from several services and return the
aggregated response.

8. Microservices Benefits and Challenges
Benefits Challenges
Independent deployments
You can update a service without redeploying the
entire application
Complexity
Independent development
A single development team can build, test, and
deploy a service.
Developing against service dependencies requires a
different approach.
Fault isolation
If a service goes down, it won't take out the entire
application.
Lack of governance
You may end up with so many different languages
and frameworks.
Mixed technology stacks Network congestion and latency
(service A calls B, which calls C...)
Granular scaling
Services can be scaled independently.
Data integrity
data consistency can be a challeng

9. In Data Storage
Relational Models
NoSql Models
Hybrid Models

10. In Deployment (Cloud)
Move to Cloud
◦ Flexibility
◦ Disaster recovery
◦ Automatic software updates
◦ Work from anywhere
◦ ……………….

11. In Deployment (Containers)

12. In Software Task
Artificial Intelligence Tasks
◦ Predictions, Clustering … etc.
◦ Analyze text ,images , any type of data
and get results

13. The Modern Software Is
Intelligent
Scalable
Distributed
