The document discusses the software development life cycle (SDLC) and its various phases and models. It describes the six main phases of the SDLC as requirements gathering and analysis, design, implementation/coding, testing, deployment, and maintenance. It then explains different SDLC models including waterfall, V-shaped, prototype, spiral, iterative incremental, big bang, and agile. The conclusion states that the best model depends on factors like requirements clarity, complexity, size, cost and skills. The waterfall model is basic but other models are variations that allow for flexibility.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.

Globus Compute wth IRI Workflows - GlobusWorld 2024Globus
As part of the DOE Integrated Research Infrastructure (IRI) program, NERSC at Lawrence Berkeley National Lab and ALCF at Argonne National Lab are working closely with General Atomics on accelerating the computing requirements of the DIII-D experiment. As part of the work the team is investigating ways to speedup the time to solution for many different parts of the DIII-D workflow including how they run jobs on HPC systems. One of these routes is looking at Globus Compute as a way to replace the current method for managing tasks and we describe a brief proof of concept showing how Globus Compute could help to schedule jobs and be a tool to connect compute at different facilities.
How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

4. Introduction:-
MM.DD.20XX
Software development life cycle is a
framework that defines the steps
involved in the development of the
software at each phase. It defines
the complete cycle of development,
all the tasks involved in planning,
creating, testing and deploying a
software product.

5. SOFTWARE DEVELOPMENT LIFE CYCLE
• Requirement gathering and analysis
• Design
• Implementation or coding
• Testing
• Deployment
• Maintenance
Different phases in SDLC
6. 1. Requirement gathering and
analysis
In this phase all the relevant information is collected from the
customer to develop the software as per their expectation.
Once all the requirement is cleared, software requirement
specification (SRS) document is created.
In this phase the information gathered in SRS document is
used as input and software architecture, that is used for
implementing system development derived.
2. Design
7. 3. Implementation or coding:-
When developer gets the design document, the software
design is translated into source code, which is called
implementation or coding.
All the component of the software are implemented in this
phase
4. Testing:-
Once coding is complete, modules are ready for the testing
phase. In this phase, the developed software is tested
thoroughly and if any defect is found, developer fix it.
8. 6. Maintenance
Software is deployed in the production environment after testing phase, or
first UAT (user acceptance testing) is done as per customer expectance.
According to UAT, a replica of the production environment is created, and
customer along with developer does the testing. If they found the software
as expected, then sign off is provided by the customer to go live.
After deployment of the software in the production environment,
maintenance phase comes in. i.e. if any issue comes in or any problems
create or need to fix it, developer takes care of it.
5. Deployment
9. SOFTWARE DEVELOPMENT LIFE CYCLE
Different types of SDLC models
1. Waterfall model
2. V-shaped model
3. Prototype model
4. Spiral model
5. Iterative incremental model
6. Big bang model
7. Agile model

1. Waterfall model:- In this model, the
outcome of one phase is the input for the next
phase. Development of the next phase starts
only when the previous phase is complete.
2. V-shaped model:- In v-shaped model
validation and verification process takes hand
to hand. i.e. planning and testing goes parallel.

3. Prototype model:- Prototype models
have limited functional capabilities and
inefficient performance when compared to the
actual software. Dummy functions are used to
create prototypes.
4. Spiral model:- The spiral model is another
important SDLC model that came into use when the
iteration in product development came into the
applied concept. This model supports risk handling,
and the project is delivered in loops. Each loop in the
Spiral model is the phases of the software
development process.Requirement

Final product
Refined

evaluation
12. 5. Iterative Incremental Model:- The iterative incremental model divides the product
into small chunks. Each iteration goes through the phases namely Requirement Analysis,
Designing, Coding, and Testing. Detailed planning is not required in iterations.
Iterative & Incremental Development Model has different phases:-
• Inception phase:- This phase includes requirement and scope of the project
• Elaboration Phase:- In this phase working architecture is delivered.
• Construction Phase:- In this phase coding and testing process are done.
• Transition Phase:- In the Transition Phase, the product is deployed in the Production
environment.
6. Big bang model:- Big Bang Model does not require much planning and scheduling. The
developer does the requirement analysis & coding and develops the product as per his
understanding. This model is used for small projects only. There is no testing team and no formal
testing is done, and this could be a cause for the failure of the project.
13. 7. Agile model:- Agile Model is a combination of the Iterative and incremental model. In Agile, a
product is broken into small incremental builds. It is not developed as a complete product in one go. Each
build increments in terms of features. The next build is built on previous functionality.

14. Conclusion:- Different Software Development Life Cycle models have their own Pros and
Cons. The best model for any Project can be determined by the factors like Requirement (whether
it is clear or unclear), System Complexity, Size of the Project, Cost, Skill limitation, etc.
In case of an unclear requirement, Spiral and Agile models are best to be used as the required
change can be accommodated easily at any stage.
Waterfall model is a basic model and all the other SDLC models are based on that only.
