O que é SaaS? Tudo o que você precisa saber sobre Software as a Service

Software as a Service explicação
Software as a Service, também conhecido como SaaS, é um serviço baseado em nuvem onde, em vez de baixar o software do seu PC de mesa ou rede comercial para executar e atualizar, você acessa um aplicativo por meio de um navegador da Internet. O aplicativo de software pode ser qualquer coisa, desde software de escritório a comunicações unificadas entre uma ampla gama de outros aplicativos de negócios disponíveis.
Isso oferece uma variedade de vantagens e desvantagens. As principais vantagens do SaaS incluem acessibilidade, compatibilidade e gerenciamento operacional. Além disso, os modelos SaaS oferecem custos iniciais mais baixos do que o download e a instalação de software tradicional, tornando-os mais disponíveis para uma gama mais ampla de empresas, tornando mais fácil para empresas menores interromper os mercados existentes enquanto capacita os fornecedores.
A principal desvantagem dos aplicativos SaaS é que eles normalmente requerem uma conexão com a Internet para funcionar. No entanto, a crescente disponibilidade de ofertas de banda larga e redes de telefonia de alta velocidade, como 5G, torna isso menos problemático. Além disso, alguns aplicativos SaaS possuem um modo offline que permite a funcionalidade básica.
Aqui, examinaremos mais de perto algumas das principais vantagens e desvantagens dos aplicativos SaaS e, em outros recursos, ajudaremos a explicar a infraestrutura como serviço (IaaS) e a plataforma como serviço (PaaS) relacionadas .
Vantagens do SaaS
Acessibilidade : uma grande vantagem de qualquer aplicativo SaaS é a capacidade de ser executado por meio de um navegador da Internet , portanto, não importa qual sistema operacional é usado para acessá-lo. Portanto, independentemente de o usuário estar tentando executar o aplicativo em máquinas Windows , Mac ou Linux (ou mesmo em smartphones com Android ou iOS), o aplicativo ainda permanece acessível. Isso torna os aplicativos SaaS incrivelmente versáteis de duas maneiras diferentes.
Por um lado, significa que você não precisa se preocupar se o seu sistema operacional ou outro software será compatível com os aplicativos SaaS. Talvez mais importante, eles não só podem ser usados no escritório em computadores desktop , mas também em dispositivos móveis, como tablets . Os aplicativos SaaS são totalmente projetados para serem compatíveis com dispositivos móveis, de modo que possam ser usados em uma ampla gama de situações e circunstâncias, inclusive em trânsito.
Atualizações e patches : outra vantagem importante dos aplicativos SaaS é que, por serem executados na nuvem, o fornecedor pode atualizar seu software centralmente sem afetar adversamente as operações de negócios para os usuários. Isso está em total contraste com o software local, que geralmente exige um certo grau de compatibilidade e teste de segurança de endpoint antes mesmo de atualizações e patches de rotina serem aplicados.
O modelo SaaS, portanto, evita as armadilhas de teste que retarda o ciclo de desenvolvimento e acesso a novos recursos para os usuários, garantindo que as atualizações de segurança sejam aplicadas o mais rápido possível, em contraste com o software local que pode permanecer vulnerável a ataques até o TI a equipe de gerenciamento de serviços concluiu seus testes.Propaganda
Hardware : isso leva a um dos outros maiores argumentos de venda sobre SaaS, que é a falta de investimento inicial necessário para usá-lo. Para software local, às vezes não é simplesmente que PCs comerciais ou outros desktops tenham software e configurações de hardware compatíveis, mas também servidores adicionais e switches de rede que podem ser necessários como parte de um investimento geral em serviços de infraestrutura de TI necessários para dar suporte ao software em toda a empresa.
O SaaS elimina essa necessidade, o que significa que até mesmo a menor empresa agora pode ter acesso a ferramentas de software por meio de aplicativos em nuvem baseados em SaaS que originalmente apenas as empresas podiam construir.
Além disso, o SaaS é escalonável, pois se você precisar adicionar mais usuários ao seu serviço ou, inversamente, reduzi-los, basta ajustar seu plano de faturamento de acordo – em vez de ter que comprar mais hardware durante a expansão, ou então ter que arquivar aparelhos eletrônicos caros quando a necessidade reduzida torna redundante.
Alcance de mercado : Para os fornecedores, isso significa ser capaz de fornecer um serviço de software para a maioria do mercado, em vez de apenas um segmento de mercado limitado e direcionado. Isso significa que os preços podem ser mais baratos e mais acessíveis para empresas de todos os tamanhos. Para os usuários, isso significa poder acessar serviços não disponíveis normalmente, expandindo e melhorando os serviços de negócios, a produtividade e as oportunidades gerais.
Economia e armazenamento : o armazenamento local de dados significa a necessidade de investir em backups confiáveis, como por meio de armazenamento online em nuvem ou outro plano de recuperação de desastres para mitigar qualquer falha grave de hardware que poderia causar perda significativa de dados. No entanto, com SaaS, os dados são rotineiramente salvos na nuvem de qualquer maneira. O que torna essa dupla vantagem não é apenas o aspecto da redundância, mas também o fato de os funcionários poderem alternar entre os dispositivos sem perder trabalho ou dados, simplesmente pelo fato de efetuarem login na conta única, independentemente do dispositivo que esteja sendo utilizado.
Dados e análises : como tudo é executado por meio de uma plataforma centralizada, isso significa que é fácil capturar dados e fornecê-los para uso analítico . As empresas que usam software SaaS geralmente têm acesso a relatórios e ferramentas de inteligência e visualizações que podem fornecer percepções valiosas sobre as operações de negócios, permitindo que os fluxos de trabalho sejam simplificados e que a economia de eficiência seja acionada. Para o fornecedor, como o acesso depende de uma assinatura paga, não há necessidade de se preocupar com a pirataria que, de outra forma, poderia custar ao fornecedor e prejudicar o acesso e os modelos de preços.
Um exemplo para nunca esquecer
Sabe aquela ferramenta SAAS que você utiliza todos os dias e não sabe? O nome desse serviço é NETFLIX, você assina o serviço, não compra um software ou marca.
