In order to optimize server performance for whatsoever reason, you need to start by monitoring the server. In most cases, before server monitoring commences, it is common practice to establish baseline performance metrics for the specific server. Baseline performance metrics are established by measuring the performance of a particular server under various conditions, at different times of the day, week, and month, and when the hardware and software configuration changes. Based on the baseline metrics which you define for the server, you would need to optimize the server when performance of the server by far exceeds your baseline metrics.

In DiDi Chuxing Company, which is China’s most popular ride-sharing company. we use HBase to serve when we have a bigdata problem.
We run three clusters which serve different business needs. We backported the Region Grouping feature back to our internal HBase version so we could isolate the different use cases.
We built the Didi HBase Service platform which is popular amongst engineers at our company. It includes a workflow and project management function as well as a user monitoring view.
Internally we recommend users use Phoenix to simplify access.even more,we used row timestamp;multidimensional table schema to slove muti dimension query problems
C++, Go, Python, and PHP clients get to HBase via thrift2 proxies and QueryServer.
We run many important buisness applications out of our HBase cluster such as ETA/GPS/History Order/API metrics monitoring/ and Traffic in the Cloud. If you are interested in any aspects listed above, please come to our talk. We would like to share our experiences with you.

One of the most often overlooked, and yet most powerful features of WebLogic is WLST, the WebLogic Scripting Toolkit.
This jython based library allows you to connect to and interact with a weblogic domain; making configuration changes, deploying applications, creating new servers and doing anything else that you might do through the console.
By scripting our domain builds and deployments, we can control our configuration and provide increased confidence in our ability to rebuild an environment in a DR scenario, and with automated deployment tools like puppet gaining traction in DevOps circles, the ability to completely script both the creation of the domain, and deployment of the application gives us great power.
This presentation will look at how WLST can be used to build a domain, deploy an application, and then provide runtime monitoring.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
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).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
UiPath Test Automation using UiPath Test Suite series, part 3DianaGray10
Welcome to UiPath Test Automation using UiPath Test Suite series part 3. In this session, we will cover desktop automation along with UI automation.

Deepak Rai, Automation Practice Lead, Boundaryless Group and UiPath MVP
2. Scalability vs. Performance
• Ratio of the increase in • Serving a single request in the
throughput to an increase in shortest amount of time
resources • Inverse of latency
• Support additional users at the
least incremental cost
• Predictability of application
behavior as users are added
3. Scalable Performance
• Number of requests that can be concurrently served
(throughput) while meeting a minimum level of service
(response time)
• Measuring:
o Resource utilization
o Throughput
o Response time
4. Horizontal vs. Vertical Scaling
• Increase the hardware resources • Improve hardware capabilities
• Separate types of processing into (cpu, RAM, storage, etc…)
tiers • No network bottleneck
• Commodity hardware is a • Becomes increasingly expensive
predictable cost per user • Practical and financial limitations
• Limitations to scaling are dictated to the ability to scale
by application architecture • Typically increases performance
• Can degrade performance
6. General Observations
• Performance decreases in each later tier (LB > web > app >
DB) due to increasing complexity
o Service requests in the earliest possible tier
• Costs of scalability increases in each later tier (LB < web <
app < DB)
o Architect bottlenecks in the earliest possible tier
• Scalable performance is ultimately limited by the operations
that do not scale linearly
• Ideally, each request that makes it to the database tier
would have its own connection
o Realistically, this means serving requests in earlier tiers because of
constraints to db scaling
10. Resource Capacity Settings
• Database CPUs
• Database connection pool
• Application server CPUs
• Application server thread pool
• JVM Heap settings
• Web server thread pool
11. Resource Capacity Settings
• Walk through the application architecture and identify the
points where a request could potentially wait.
• Open all wait points.
• Generate balanced and representative load against the
environment.
• Identify the limiting wait point’s saturation point.
• Tighten all wait points to facilitate only the maximum load of
the limiting wait point.
• Force all pending requests to wait at the Web server.
• Add more resources.
12. Profiling
• Long running http requests
• Long running methods
• Memory leaks
• Deadlocks
• Long running queries
13. Database Tier
• System of record
• Difficult to scale horizontally and expensive to scale
vertically
• Keep connections limited to what the server will support
o Block at the app tier
• Perform data processing on staging server
• Each database has its own optimization techniques
o Explain plan to locate and eliminate full table scans
o Query and table caches
o Buffer sizes
14. Application Tier
• Generally cannot be stateless due to security and business
requirements
• Sticky vs. clustered sessions
o Use the HTTPSession sparingly
o If the app does not need to be HA, it may not require clean failover
and can drop sessions
• Scaling horizontally could potentially put more load on the
DB
o Caching can be used to offset the load
15. Application Caching
• Read-only data can be cached like static data in the web
tier
• Write-able data can be cached but will impose limitations on
clustering
o Will probably either need to be in-sync across the cluster or turned off
completely
• Filters can provide caching of dynamic, secure data at the
earliest point in this tier
o Caches entire response
o Not recommended for user-specific data
• Service layer or data access caches provide a simple way
to stop requests from continuing to the database
o Transparent to the calling code
o Cache interceptors
16. Tomcat Tuning
• maxThreads controls actively served connections
• backlog controls the number of connections that can be
queued
• maxThreads + backlog = total accepted connections
• connectionTimeout can be used to drop faulty connections
• bufferSize is by default set to -1, no buffering of output
• Keep heap size manageable, < 2GB
17. Web Tier
• Clustering is easiest in the web tier because they are
generally stateless
• Web tier clustering can provide super-linear scaling (IO
contention, context switching costs)
• The web tier should serve all static data (images, static
html)
• The web tier can serve dynamic requests by caching non-
secure data that only depends upon url parameters
o Squid reverse proxy
o Apache mod cache
o Memcached
18. Apache Tuning
• Limit connections in the web tier to prevent overloading
later tiers (MaxClients)
• ServerLimit x Memory per process < RAM available to limit
swapping
• Avg connections = ThreadsPerChild x Apache hosts / App
Server hosts
• ProxyPass max = ThreadsPerChild
19. Other
• Grid Caches
o GigaSpaces
o Coherence
• CDN
o Akamai
• Compute Appliances
o Azul Systems
