Private Cloud Architecture
The document discusses the private cloud architecture being implemented at the University of the Witwatersrand. It outlines plans to build a private cloud infrastructure using open source technologies like OpenStack, Fedora, iRODS and Zimbra. The cloud will provide scalable compute and storage resources along with hosted services and a digital archive. Key steps are identifying support staff, collaborating with technology partners, and having the initial infrastructure in place by mid-November.
Optimization of Resource Provisioning Cost in Cloud Computing
In cloud computing, cloud providers can offer cloud consumers two provisioning plans for computing resources, namely reservation and on‐demand plans. In general, cost of utilizing computing resources provisioned by reservation plan is cheaper than that provisioned by on‐demand plan, since cloud consumer has to pay to provider in advance. With the reservation plan, the consumer can reduce the total resource provisioning cost. However, the best advance reservation of resources is difficult to be achieved due to uncertainty of consumer's future demand and providers' resource prices. To address this problem, an optimal cloud resource provisioning (OCRP) algorithm is proposed by formulating a stochastic programming model. The OCRP algorithm can provision computing resources for being used in multiple provisioning stages as well as a long‐term plan, e.g., four stages in a quarter plan and twelve stages in a yearly plan. The demand and price uncertainty is considered in OCRP. In this paper, different approaches to obtain the solution of the OCRP algorithm are considered including deterministic equivalent formulation, sample‐average approximation, and Benders decomposition. Numerical studies are extensively performed in which the results clearly show that with the OCRP algorithm, cloud consumer can successfully minimize total cost of resource provisioning in cloud computing environments.
Pervasive Computing
Pervasive computing also known as Ubiquitous computing (ubicomp) is a concept in software engineering and computer science where computing is made to appear everywhere and anywhere. Eg:laptop computers, tablets and terminals in everyday objects such as a fridge or a pair of glasses.
•It is also termed as ambient intelligence, Ubiquitous computing ,everyware,physical computing, the Internet of Things, haptic computing, and 'things that think’.
Cloud computing
Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. It allows companies to access computing resources over the Internet rather than build and maintain computing infrastructures themselves. Major benefits of cloud computing include flexibility, disaster recovery, automatic software updates, increased collaboration, and the ability to work from anywhere. Several telecom companies, such as Orange, Etisalat, Vodafone, and Ericsson, provide cloud computing services to help businesses move online to enhance performance and efficiency.
What is private cloud Explained
A private cloud is a type of cloud computing that provides scalability and self-service capabilities like a public cloud but within a proprietary infrastructure dedicated to a single organization. It is a single-tenant environment where the organization does not share resources with other users. Private clouds can be hosted internally or by third-party providers and offer increased security, performance, and customization compared to public clouds but at a higher cost and with less scalability. Common types include virtual private clouds, managed private clouds, and on-premise private clouds. Major vendors include Cisco, Google, AWS, IBM, and Microsoft.

It also addresses key security concerns including governance, legal issues, compliance, information lifecycle management, and risks associated with loss of control over data and applications in the cloud. The document emphasizes that security responsibilities are shared between cloud providers and users, and both parties need to understand their roles.
Fog Computing
The term “fog computing” or “edge computing” means that rather than hosting and working from a centralized cloud, fog systems operate on network ends. It is a term for placing some processes and resources at the edge of the cloud, instead of establishing channels for cloud storage and utilization.
Azure vnet
An Azure Virtual Network (VNet) provides logical isolation within Azure to securely communicate resources. A VNet can connect to other VNets or on-premises networks. It contains components like network security groups, load balancers, and virtual appliances to filter and optimize traffic flow. Connections to a VNet can be made through point-to-site VPNs, site-to-site VPNs, or Azure ExpressRoute for private, high-bandwidth connections.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
