Le soluzioni tecnologiche per il Copy Data ManagementJürgen Ambrosi
L'incremento dei dati presenti sui sistemi aziendali impone all’IT di confrontarsi con l’aumento della complessità e dei costi che ne derivano per l’adeguamento tecnologico.
Uno dei motivi principali che causano l’aumento dei dati è tuttavia rappresentato dalla sempre più frequente richiesta di copie attendibili e rapide degli stessi, per far fronte alle diverse esigenze di business nell’avvio di nuovi progetti o di routine come test, archiviazione, backup, disaster recovery, reporting, ecc. Inoltre molto spesso non si ha il pieno controllo di chi ha accesso agli storage per eseguire tali copie con evidente esposizione a rischi di sottrazione illecita dei dati.
Venendo incontro a tale tipo di necessità, Veritas presenta Velocity, la propria soluzione di Copy Data Management che permette di ottenere in tempi rapidi copie di dati con accesso automatizzato e controllato, evitando inutili proliferazioni di copie e conseguente esposizione a rischi di atti fraudolenti.

What is NetBackup appliance? Is it just NetBackup pre-installed on hardware?
The answer is both yes and no.
Yes, NetBackup appliance is simply backup in a box if you are looking for a solution for your data protection and disaster recovery readiness. That is the business problem you are solving with this turnkey appliance that installs in minutes and reduce your operational costs.
No, NetBackup appliance is more than a backup in box if you are comparing it with rolling your own hardware for NetBackup or if you are comparing it with third party deduplication appliances. Here is why I say this…
NetBackup appliance comes with redundant storage in RAID6 for storing your backups
Symantec worked with Intel to design the hardware for running NetBackup optimally for predictable and consistent performance. Eliminates the guesswork while designing the solution.
Many vendors will talk about various processes running on their devices to perform integrity checks, some solutions even need blackout windows to do those operations. NetBackup appliances include Storage Foundation at no additional cost. The storage is managed by Veritas Volume Manager (VxVM) and presented to operating system through Veritas File System. Why is this important? SF is industry-leading storage management infrastructure that powers the most mission-critical applications in the enterprise space. It is built for high-performance and resiliency. NetBackup appliance provides 24/7 protection with data integrity on storage provided by the industry leading technology.
The Linux based operating system, optimized for NetBackup, harden by Symantec eliminates the cost of deploying and maintaining general purpose operating system and associated IT applications.
NetBackup appliances include built-on WAN Optimization driver. Replicate to appliances on remote sites or to the cloud up to 10 times faster on across high latency links.
Your backups need to be protected. Symantec Critical System Protection provides non-signature based Host Intrusion Prevention protection. It protects against zero-day attacks using granular OS hardening policies along with application, user and device controls, all pre-defined for you in NetBackup appliance so that you don’t need to worry about configuring it.
Best of all, reduce your operational expenditure and eliminate complexity! One patch updates everything in this stack! The most holistic data protection solution with the least number of knobs to operate.
RAID protects disk drives, not data. Yet RAID rebuild times have become an unmanageable liability. RAID is an equal opportunity failure risk for any vendor's high-capacity drives deployed at scale.

A perspective on the growth and usage of Flash, a comparison to birth and growth of motor car to that of Storage Array's and the need for Open source software
Is Software Defined Storage (SDS) getting hijacked? It seems every vendor, old and new, is claiming that their storage is “software defined”. The original intent was to create software-only solutions that could be deployed on the customer’s choice of servers. But that original intent has evolved, and now hardware vendors are providing what they claim to be software defined storage solutions too. In addition, SDS is being combined with an embedded compute function to create hyper-converged solutions as well.
In this webinar we will discuss the differences in these approaches and you will learn what the four key deliverables of a SDS solution should be so you can decide which makes the most sense for your organization.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
Removing Uninteresting Bytes in Software FuzzingAftab Hussain
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.
- These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

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.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance.

The data center of today is transforming to become increasingly virtualized, and next-generation data centers will incorporate more public, private, and hybrid cloud-based applications. Virtualization and cloud bring server consolidation, workload mobility, self-provisioning, management, multi-tenancy, and the ability to rapidly scale up and out.
Organizations continue to look for ways to simplify operations, increase resource utilization, and improve TCO in IT. When asked what their most important storage challenges were, more than half of respondents to an ESG survey said capital expenses and more than one third said operational expenses.
What’s driving these spending trends?
After hardware costs, the rapid growth of data and the subsequent requirements to protect that data were the most commonly cited storage challenges.
This makes sense in light of the fact that managing data growth and improving backup and recovery—both with obvious storage implications—were among the top five most-cited overall IT priorities in ESG’s 2016 IT Spending Intentions Survey.
In a hybrid configuration, SanDisk Optimus Ascend SSDs serve as read-and-write cache, and magnetic disks provide the data store capacity.
In an all-flash configuration, Optimus Ascend SSDs are used for write caching and SanDisk Optimus Max SSDs provide data store capacity. No read caching is provided because the read performance from the Optimus Max SSDs is more than sufficient.
The test bed represents a common configuration for VMware Virtual SAN, and includes four industry-standard x86 servers, each running VMware Virtual SAN 6, which aggregated all storage resources into a single virtual data store.
For the hybrid configuration, each physical server was configured with 16 drives, split into two disk groups of eight drives each. Each disk group was composed of seven industry-standard 1.2TB 10K RPM magnetic SAS drives for storage capacity, and one 800GB SanDisk Optimus Ascend SSD for the read and write cache.
For the all-flash configuration, each physical server was configured with six drives, split into two disk groups of three drives each. Each disk group was composed of two SanDisk Optimus Max 4TB SSDs for storage capacity, and one 800GB SanDisk Optimus Ascend SSD for write acceleration.
Eight virtual machines,, were running Microsoft Windows Server 2012 R2 and Microsoft SQL Server 2014. Each VM was configured to have 16 virtual CPUs and 96 GB of RAM.
ESG simulated a typical OLTP workload using HammerDB, an industry-standard, open source database load testing and benchmarking tool.
The workload was composed of ten transaction types with a defined ratio of execution. Four of the transactions performed database updates, and the rest were read only.
ESG Lab started the test with a five-minute ramp to reach steady state operations. Once steady state was achieved, the test ran for 30 minutes.
We measured more than 1.7 million new orders per minute for the hybrid configuration.
The all-flash configuration delivered 49% better performance, at more than 2.5 million new orders per minute.
Digging in to the details, the hybrid configuration showed some variability, with a close-to-even workload distribution across SQL servers.
The all-flash configuration yielded higher levels of performance with less variability and therefore better workload distribution.
Using street prices for the cost of the servers, software licenses, magnetic disks, and SanDisk SSDs, The all-flash solution was 10% more expensive than the hybrid solution, and delivered 49% better performance.
Combing price and performance, the all-flash solution was 26% less for on a price per new orders per minute basis, reflecting the price/performance advantage of a SanDisk-powered all-flash Virtual SAN solution.
It would take an additional $164,000 investment in a hybrid solution to achieve the performance of the all-flash solution.
Lets double click on Hyper-Converged Infrastructure.
Hyper-Converged Infrastructure (HCI) leverages the hypervisor to deliver compute, networking and shared storage from a single x86 server platform. The software-driven architecture allows the convergence of physical storage onto commodity x86 servers, enabling a building block approach with scale-out capabilities. The use of commodity x86 server and storage hardware allows datacenters to operate with agility on a highly scalable, cost-effective infrastructure.
How VMware Enables Hyper-Converged Infrastructure
The foundational components of VMware’s HCI solution are VMware vSphere and VMware Virtual SAN, which allow the convergence of compute, storage and networking onto a single, integrated layer of software that, can run on any commodity x86 infrastructure. vSphere abstracts and aggregates compute and memory resources into logical pools of compute capacity while Virtual SAN, embedded in vSphere, pools server-attached storage to create a high performance, shared datastore for virtual machine storage.
Customers can further extend vSphere to achieve the convergence of networking using VMware NSX which decouples network resources from underlying hardware and brings the operational model of a virtual machine to the datacenter network.

Virtual SAN is VMware’s software-defined storage solution, built from the ground up for vSphere virtual machines. It abstracts and aggregates locally attached disks in a vSphere cluster to create a storage solution that can be provisioned and managed from vCenter and the vSphere Web Client.
Virtual SAN is hypervisor-converged – that is – storage and compute for VMs are delivered from the same x86 server platform running the hypervisor. It integrates with the entire VMware stack, including features like vMotion, HA, DRS etc. VM storage provisioning and day-to-day management of storage SLAs can be all be controlled through VM-level policies that can be set and modified on-the-fly.
Virtual SAN delivers enterprise-class features, scale and performance, making it the ideal storage platform for VMs.
VMware’s Storage Policy Based Management framework allows you to define storage requirements on a per-VM basis, based on the needs of the applications running in the VMs.
Simply define the amount of capacity, performance and availability for each VM
Virtual SAN then matches those defined requirements to underlying storage infrastructure.
Unlike traditional external storage, where provisioning is done at storage array layer, in a more rigid-hardware-centric way… Virtual SAN puts the application in charge, and allows you to provision and control storage in an application-centric way
Virtual SAN software abstracts underlying hardware and automates ongoing management of the storage SLAs assigned to VMs
End result => No more LUNs of Volumes…
This simplifies storage management…. And as you will see, saves you time and money.
WRITES:
Each write first goes to a flash device. It is then de-staged to the data persistence tier (Magnetic disks in Hybrid architecture and flash devices in All-Flash architecture). When creating replicas, the writes for each replica to the flash devices is
Virtual SAN WITNESS: Witness components—those that contain only object metadata—are part of every storage object. A witness serves as a tiebreaker, to avoid split-brain behavior when availability decisions are made in the Virtual SAN cluster. Each Virtual SAN witness component also consumes 2MB of capacity.
Virtual SAN enables both hybrid and all-flash architectures.
Irrespective of the architecture, there is a flash-based caching tier which can be configured out of flash devices like SSDs, PCIe cards, NVMe etc. The flash caching tier acts as the read cache/write buffer that dramatically improves the performance of storage operations.
In All-Flash architecture, the flash-based caching tier is intelligently used as a write-buffer only, while another set of SSDs forms the persistence tier to store data. Since this architecture utilizes only flash devices, it delivers extremely high IOPs of up to 100K per host, with predictable low latencies. Reads will primarily come from the capacity tier, although if data was freshly written is “hot” and not de-staged it may read from the write cache tier.
In the hybrid architecture, server-attached magnetic disks are pooled to create a distributed shared datastore, that persists the data. In this type of architecture, you can get up to 40K IOPs per server host.
Typical hardware component mean time between failures is between 1M to 2M hours – providing about 2x9s availability level
By replicating components across the cluster, between rack or sites - Virtual SAN exponentially increases the availability
With default availability policy of Failures to Tolerate (FTT) of 1, Virtual SAN delivers 5x9s protection
Increasing the availability policy to FTT=2 results in 6x9s protection – it’s more likely to lose data from a natural disaster than losing 3 hardware components at the same time
Best part is that you get to choose the level availability for every VM. Better yet, you can change it whenever you like and VSAN will make the changes automatically.
Virtual SAN is built from the ground up for vSphere environments and its core value proposition revolves comes from the following key strengths:
Radically Simple
It is embedded in the VM kernel and does not need to be installed like a storage appliance. Just 2 clicks and its enabled!
It uses storage policies to assign storage services to specific VMs. It then automatically tunes and rebalances storage to ensure that the VM storage SLAs stay compliant with the policies throughout the lifecycle of the VM.
It is managed through the same web interface as the rest of your vSphere environment. This makes it easy for even the VI Admin to manage storage and eliminates the need for specialized skillsets.
It is completed integrated into VMware stack, and works seamlessly with other vSphere features and VMware products.
One software stack, one vendor
No physical storage silo
Policy-driven management
Integrated workflows
High Performance
VSAN 6.0 introduced a new flash architecture for caching and data persistence. This provides the ability to get high IOPS with consistently low latencies suitable for business-critical or transaction processing applications that require consistent response times
It is embedded in ESXi kernel and therefore optimizes the data I/O path better than other technologies that need a storage virtual appliance
One of VSAN’s core advantages is its ability to scale performance and capacity in a linear and predictable manner: both scale-out or scale-up by adding flash, magnetic disks or hosts as needed
Up to 90k IOPs per host
All-flash for sub-ms response
Predictable, elastic scaling
1.5 – 5x faster than competitors
Lowers TCO by as much as 50%
VSAN has a hardware independent architecture which can utilize cheaper server-side, industry-standard components to reduce storage capex; the scaling and purchasing in chunks allows the flexibility to change vendors or hardware over time, ensuring you use the latest available on the market
Grow-as-you-go scaling allows investments to be spread over time in a more cost-effective manner
Last but not least, its VMware integration, policy-driven control and automation make it operationally efficient, saving even more dollars in the long run
