Presentation by Assoc.Prof. Dr.Thanachart Numnonda & Asst.Prof. Thanisa Kruawaisayawan, Mini Master of Java Technology KMITL, July 2012
The presentation covers overview of Azure App Service and Azure Web Apps. The presentation also covers the different features of Azure Web Apps - like Kudu, Continuous Deployment, Application Insights, Deployment Slots, Auto-Scaling and so on including demos. It will be useful for anyone looking forward to learn about Azure Web Apps or anyone preparing for Azure Certifications (70-532/533).
The Java ecosystem is very broad, with different technologies including Java SE, Java EE/Jakarta EE, Spring, numerous application servers, and other frameworks. Wherever you are in Java, Azure supports your workload and process with an abundance of choice – from IaaS to fully managed services. You can run any application architecture, from monoliths, to containerized monoliths, all the way to completely microservices based apps.
We see three broad patterns for running Java applications in the cloud, depending on how much control or productivity you need.
The first is lift and shift with Virtual Machines:
Virtual machines provide the most flexibility, control and visibility while moving to the cloud, especially for initial lift and shift of Java workloads. Azure provides a variety of Java focused VM images and solutions templates in the Azure Marketplace to get you up and running quickly.
The second is modernization using containers:
Containers provide portability, flexibility, scalability, manageability, repeatability, and predictability.
Azure provides best of breed support for Docker and Kubernetes, especially through the Azure Kubernetes Service (AKS) and Azure Red Hat OpenShift.
Finally, Azure has the most managed hosting options for Java applications of any major cloud platform with fully managed PaaS for Spring, Tomcat, and JBoss EAP:
Managed services offer ease-of-use, ease-of-management, productivity, and lower total cost of ownership.
You can focus on building your applications, not managing infrastructure.
All of this is supported by managed databases and DevOps tooling:
Use fully managed SQL and NoSQL databases, including PostgreSQL, MySQL, Cosmos DB, and SQL.
Keep using the tools you love, with plugins for IntelliJ and Eclipse, integrations with a variety of DevOps tools like Maven, Gradle, Jenkins, and GitHub.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
4. Cloud computing : Definition (Wikipedia)
Cloud Computing is Internet-based computing,
whereby shared resources, software, and information
are provided to computers and other devices on
demand, like the electricity grid.
5. Cloud computing characteristics
Massive, abstracted infrastructure
Dynamic allocation, scaling, movement of applications
Pay per use
No long-term commitments
OS, application architecture independent
No hardware or software to install
7. Web 2.0 & Cloud Computing
Web 2,0 concentrate on the private user and clouds
are decscendents of data centers which services the
enterprise
Web 2.0 promote SaaS
Web 2.0 needs massive scaling technologies
User centric Web 2.0 companies (Twitter, Slideshare)
are relying on Cloud Services
9. Software as a Service (SaaS)
SaaS is at the highest layer and features a complete
application offered as a service, on-demand,
via multitenancy — meaning a single instance of the
software runs on the provider’s infrastructure and
serves multiple client organizations.
10. Platform as a Service (PaaS)
The middle layer, or PaaS, is the encapsulation of a
development environment abstraction and the
packaging of a payload of services
PaaS offerings can provide for every phase of software
development and testing, or they can be specialized
around a particular area, such as content management
11. Infrastructure as a Service (IaaS)
IaaS is at the lowest layer and is a means of delivering basic
storage and compute capabilities as standardized services
over the network.
Servers, storage systems, switches,routers, and other
systems are pooled (through virtualization technology, for
example) to handle specific types of workloads — from batch
processing to server/storage augmentation during peak loads.
12.
13. Deployment Model
Public Cloud: provider refers to the cloud platform that
targets any types of customers.
Private Cloud: infrastructure that’s hosted internally, targeting
specific customers or sometimes exclusively within an
organization.
Hybrid Cloud: the combination of public and private clouds,
or sometimes on-premise services.
14. IaaS & PaaS: Developer's Perspectives
IaaS normally provides up to O/S level as your choice; for
example Amazon Web Services (AWS) offers several types of
Operating Systems such as Windows Server, Linux SUSE, and
Linux Red Hat. Developer need to install own middleware,
database, etc.
PaaS, given that the database server, VM, and web server VM
are readily provisioned,

17. PaaS for Java
Amazon Elastic Beanstalk
CloudBees
Cloud Foundry
Google App Engine
Heroku for Java
Red Hat OpenShift
21. Google App Engine : Definition (Wikipedia)
It is a platform for hosting web applications in Google-
managed data centers. It is cloud computing
technology which virtualizes applications across
multiple servers and data centers.
22. Google App Engine
Running your web application in Google infrastructure
Support different runtime environments
Java (JRE 6 with limitation, Servlet 2.5, JDO, JPA)
Python (2.5.2)
Apps run in sandbox.
Automatic scaling and load balancing
No server restart, no network issues
23. Hosting Java web apps traditionally
Not so popular except enterprise
High rates as compared to PHP hosting
Shared Tomcat instance among users
Restrictions on any time deployments due to shared
server
Dedicated hosts works fine but they are costly
37. App Engine for Java : One Year
Source: What’s Hot in Java for App Engine Google Con 2010
38. GAE Java Runtime Environment
Java 6 VM
Servlet 2.5 Container
HTTP Session support (need to enable explicitly)
JDO/JPA for Datastore API
JSR 107 for Memcache API
javax.mail for Mail API
javax.net.URLConnection for URLFetch API
40. Services by App Engine
Memcache API – high performance in-memory key-value cache
Datastore – database storage and operations
URLFetch – invoking external URLs
Mail – sending mail from your application
Task Queues – for invoking background processes
Images – for image manipulation
Cron Jobs – scheduled tasks on defined time
User Accounts – using Google accounts for authentication
41. Limitations
Programming Model : Application runs in sandbox and
can not
Write to file system
Make arbitrary network connections
Use multiple threads/processes
Perform long-lasting processing
Permissions
Know about other instances/applications
Quotas (Requests, In/Out bandwidth, CPU time, API
calls)
43. GAE Datastore
Storing data and manipulation
Based on Bigtable
Bigtable is proprietary and hidden from the app developers
Not a relational database (No SQL)
GQL (Google Query Language) to query
Stores data as entities
Distribution, replication, load balancing behind the scene
Need to use JDO/JPA
44. User Service : Google Accounts
Google Accounts are encouraged as the preferred
authentication mechanism for App Engine
– It assumes that all users have a Google Account
– Google authentication for private domains isn’t available yet
Access to Google account data -> email, id
The Development Server simulates Google Accounts
Access constraints based on roles
45. User API : Example
import com.google.appengine.api.users.*;
import com.google.appengine.api.users.*;
UserService userService == UserServiceFactory.getUserService();
UserService userService UserServiceFactory.getUserService();
User user == userService.getCurrentUser();
User user userService.getCurrentUser();
String navBar;
String navBar;
if (user == null) {{
if (user == null)
navBar == "<p>Welcome! <a href="" ++ userService.createLoginURL("/")
navBar "<p>Welcome! <a href="" userService.createLoginURL("/")
+"">Sign in or register</a> to customize.</p>";
+"">Sign in or register</a> to customize.</p>";
}} else {{
else
navBar == "<p>Welcome, "" ++ user.getEmail() ++ "! You can <a href=""
navBar "<p>Welcome, user.getEmail() "! You can <a href=""
+userService.createLogoutURL("/") +"">sign out</a>.</p>";
+userService.createLogoutURL("/") +"">sign out</a>.</p>";
}}
46. URLFetch API

String line;
String line;
while ((line == reader.readLine()) != null) {{
while ((line reader.readLine()) != null)
//do something
//do something
}}
reader.close();
reader.close();
47. Mail API
Send emails on the behalf of app administrator to the Google
account use.
You can not receive emails
import javax.mail.*;
import javax.mail.*;
Session session == Session.getDefaultInstance(new Properties(), null);
Session session Session.getDefaultInstance(new Properties(), null);
