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:

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.

26. Histórico e Introdução a Plataforma
Mainframe
• O termo “Mainframe” se refere ao gabinete principal que alojava a unidade
central de processamento nos primeiros computadores.
• O termo é utilizado até hoje por usuários de computadores considerados como
“de grande porte”, IBM ou não IBM.
• IBM System z é o nome de um dos servidores da família de servidores da IBM
Systems and Technology Group (STG).
• IBM STG é uma unidade de negócio da IBM responsável pelos servidores e discos
(hardware e storage).
27. Histórico e Introdução a Plataforma
Mainframe
• Se a IBM não criar o software para rodar sistemas de mainframe ela mesma, a
empresa “ABC” o fará, e certamente existe um mercado muito interessado nesta
solução e assim acaba o monopólio da IBM em relação ao hardware proprietário, caro
e de museu
28. O Sistema dos Sistemas
A realidade nos dias de hoje...
Embora a tecnologia tenha feito grandes progressos e
todas as plataformas tenham evoluído muito, a demanda
e os requisitos estabelecidos cresceram
exponencialmente.
As cargas de trabalho estão mais diversificadas e
mais complexas;
Um volume de dados sem precedentes;
Maior cobrança por desempenho e eficiência;
Segurança e continuidade de negócios são essenciais.
29. O Sistema dos Sistemas A sedução pelo “one size fits all”...
Os ambientes corporativos são multiplataforma
e são otimizados para diferentes workloads:
• Banco de Dados;
• Processamento Transacional;
• Business Analytics;
• Web-based Portals;
• Enterprise Applications (como ERP);
• Inúmeras aplicações x86.
Soluções complexas são otimizadas para o funcionamento em infraestruturas de
camadas heterogêneas de software e hardware
30. O Sistema dos Sistemas
Computação Centralizada (Sistema z/OS)
Clientes trabalham com servidor a 100% de
utilização sem degradação de desempenho
Proteção de investimento
Nenhuma ocorrência de vírus ou invasão

O projeto iniciou-se em 1993 e publica uma lista atualizada a cada seis meses. A primeira atualização de cada ano é
em junho, coincidindo com a International Supercomputer Conference, e a segunda em novembro na IEEE
Supercomputer Conference.
Editor's Notes
Em 2014, no dia 8 de abril, comemoramos 50 anos do primeiro mainframe, o System 360.
Aposta de USD 5 bi em 1964.
Mudança de paradigma.
Sistemas cognitivos não devem substituir (pelo menos num futuro breve) os atuais sistemas programáveis que conhecemos.
Sistemas cognitivos, termo IBM, representados pela nova divisão denominada IBM Watson, representa essa nova era. Sistema capaz de interpretrar a fala humana, aprender através da análise de textos em inglês, e indicar respostas com um percentual de confiança.

O que essa parceria histórica significa?
Falando apenas de servidores, também foi anunciado a venda da divisão de servidores x86 para a Lenovo.
Essa é a primeira de algumas leis da computação que apresentarei durante essa 1 hora.
Esse é um gráfico retirado da literatura mostrando o efeito da chamada Lei de Moore, não do ponto de vista de transistors , mas da capacidade de processamento sequencial.
Já que vamos falar de servidores hoje…

Traditional multithreading: locks and serialization
Transactional memory is an approach to parallel programming that has the potential to make efficient parallel programming a great deal easier than it is currently. Parallel programming is easy when a task can be broken up into many independent threads that don't share any data; each part can run on a processor core, and no coordination between cores is necessary. Things get more difficult when the different parts of the task aren't completely independent—for example, if different threads need to update a single value that they share.
The traditional solution is to use locks. Every time a thread needs to alter the shared value, it acquires the lock. No other thread can acquire the lock while one thread holds it; they just have to wait. The thread with the lock can then modify the shared value (which may require a complex computation, and hence can take a long time), and then release the lock. The release of the lock in turn allows the waiting threads to continue. This system works, but it has a number of problems in practice. If updates to the shared value occur only infrequently—and hence, it's rare for a thread to ever have to wait—the lock-based system can be very efficient. However, that efficiency tends to rapidly diminish whenever updates to the shared value are frequent: threads spend a lot of their time waiting for the lock to become available, and can't do any useful work while they're waiting.
Locks also prove quite difficult for programmers to use correctly. Though the case of a single shared value is easy to handle, real programs are rarely so simple. A program with two locks, A and B, is susceptible to a problem called deadlock. If two threads need both locks, they have a choice; they can either acquire lock A followed by lock B, or they can acquire lock B followed by lock A. As long as every thread acquires the locks in the same order, there's no problem. However, if one thread acquires lock A first, and the other acquires lock B first, then the two threads can get stuck—the first waits for lock B to become free, the second waits for lock A to become free, and neither can ever succeed. This is a deadlock.
This problem might seem easy to avoid, and indeed when a program only has two locks, it normally is—but it becomes harder to ensure that every part of the program does the right thing as the program becomes more complex. Add more locks, for other bits of shared data, and it becomes harder still.
Transactional memory: the end of locks
Transactional memory is designed to solve this kind of problem. With transactional memory, developers mark the portions of their programs that modify the shared data as being "atomic." Each atomic block is executed within a transaction: either the whole block executes, or none of it does. Within the atomic block, the program can read the shared value without locking it, perform all the computations it needs to perform, and then write the value back. At the end, it commits the transaction. The clever part happens with the commit operation: the transactional memory system checks to see if the shared data has been modified since the atomic operation was started. If it hasn't, the commit just makes the update and the thread can carry on with its work. If the shared value has changed, the transaction is aborted, and the work the thread did is rolled back. Typically when this happens, the program will simply retry the operation.
Transactional memory potentially offers a number of advantages over the lock-based scheme. First, it's optimistic: instead of each thread needing to acquire a lock just in case another thread tries to perform a concurrent operation, the threads assume that they'll succeed. It's only in the case of actual concurrent modifications that one thread will be forced to retry its work. Second, there's no deadlock scenario, since there are no locks. Third, the programming model is, broadly speaking, one that developers are quite familiar with; the notion of transactions and roll-back is familiar to most developers who've used relational databases, as they offer a somewhat similar set of features. Fourth, atomic blocks arguably make it a lot easier to construct large, correct programs: an atomic block with nested atomic blocks will do the right thing, but the same isn't necessarily true of lock-based programs.
