Servidor em São Paulo: cinco perguntas antes de contratar

Uma equipe pequena pode começar definindo o que precisa atender, em vez de escolher só pelo nome do plano. Imagine uma loja ou API usada por clientes em diferentes estados do Brasil: a melhor decisão depende das redes desses clientes e dos serviços conectados à aplicação. 1. Quem usa a aplicação e em quais momentos? Anote os estados e tipos de conexão mais importantes, o horário de pico e as operações críticas, como consultar um produto ou enviar um pedido. Selecione uma configuração para comparar e confirme se ela está disponível. 2. Como testar a experiência? Em um ambiente de teste autorizado, com dados fictícios e sem executar pedidos ou pagamentos reais, compare a mesma operação HTTPS a partir de redes fixas e móveis representativas, em horários comuns e de pico. Registre tempo de resposta, falhas, data e origem do teste. O nome da cidade não garante uma rota rápida; uma única medição não representa todos os usuários. 3. Onde estão as dependências? Liste banco de dados, arma...

Manila or Singapore? A three-office checklist for testing cloud-server paths

Disclosure: UCELI provides cloud servers and domain services. This article was prepared with AI assistance. It does not claim a particular UCELI location is in stock, has a specific IP address, or will be faster for your users. A team serving people in the Philippines might consider an application hosted in Manila or Singapore. Geography alone cannot tell the team which option will work better: the answer depends on the office networks, the path to the application, the database and other dependencies, as well as cost. The example below is hypothetical . It is a small planning exercise, not a customer case study or a report of measured performance. Run tests only against systems you own or have explicit permission to test, with the service owner’s agreed limits and a non-sensitive test endpoint. Start with three representative offices Imagine a team with three offices: one whose staff mainly use a fixed office connection, one using a different provider, and one whose staff sometimes...

東京のクラウドサーバーを選ぶ前に：帯域とデータ転送量を7日間の記録から考える

この記事は、クラウドサーバーとドメインサービスを提供するUCELIの記事です。作成にはAIを使用しています。料金や在庫、通信品質を保証するものではありません。 サーバー選びで「Mbps」と「GB／月」を見かけたら、まず別のものとして考えましょう。前者はデータ転送速度、後者は一定期間にやり取りしたデータの量を表します。東京のサーバーを検討するときも、どちらか一方の数値だけで判断せず、自分の用途と契約条件を照らし合わせることが大切です。 MbpsとGBは何が違う？ Mbps ：1秒あたりのデータ転送速度を表す単位です。プランの表示が上限・保証値・目安のどれか、どの方向に適用されるか、共有帯域かどうかは契約ごとに確認してください。 GB／月 ：1か月などの期間に転送したデータの量を示す単位です。料金に含まれる量なのか、課金対象の使用量なのか、サーバーを基準とする送信（外向き）と受信（内向き）のどちらを数えるかはサービスによって異なります。 たとえば、道路の幅が広くても、1か月に通る車の台数は交通量次第です。同様に、帯域の上限だけでは、月間転送量や料金は決まりません。逆に、月間転送量が少なくても、短時間にアクセスが集中すれば帯域が足りなくなることがあります。 単位にも注意してください。小文字の b はビット、大文字の B はバイトです。1バイトは8ビットです。この記事では十進の単位を使い、1 Mbps＝毎秒100万ビット、1 GB＝10億バイトとします。 GiB は別の単位で、1 GiB＝2の30乗バイトです。単位の定義は米国国立標準技術研究所（ NISTの説明 ）を参照してください。 7日間の記録から月間量を概算する すでに運用中のサイトやアプリがあれば、まず同じ範囲の通信量を7日間記録します。可能なら平日と休日の両方を含め、計測の開始・終了時刻、対象サーバー、送信（外向き）／受信（内向き）の別、単位、データの取得元をメモします。バックアップ、監視やCDN経由の通信が集計に含まれるかも確認しましょう。 仮の計算例 として、7日間のサーバーから外へ出る通信の平均が 2 Mbps だったとします。これはプランの上限ではなく、同じ計測範囲における通信のない時間も含む604,800秒全体の時間加重平均という前提です。欠測や計測範囲の違いがある場合は、先に記...

Before you secure your first Ubuntu VPS: keep a way back in

Disclosure: UCELI provides cloud servers and domain services. This article was prepared with AI assistance. It is general educational material and does not promise that a particular UCELI image, recovery console, backup or support feature is available for your server. A firewall rule or SSH change can make a server harder for an attacker to reach—and harder for you to reach, too. Before changing remote access on a new Ubuntu VPS, make sure you can recover from a mistake and verify a new independent login. This is a planning checklist, not a copy-and-paste hardening recipe. Ubuntu versions, cloud images and network policies differ. Make changes only on systems you own or are authorized to administer, and first practice the procedure in an isolated test environment. 1. Identify your recovery route Before changing SSH or firewall settings, find out how your provider handles a lost SSH connection. Some environments offer a separate console or recovery method; availability and access re...

A practical cloud server budget: first month versus renewal

A server's headline price can be a useful starting point, but it may not represent everything your application needs to run. Before choosing a plan, make two estimates: what you expect to spend in the first month , and what you expect to spend in a normal renewal month . Keep any unknown amounts visible instead of assuming they are free. This checklist is for a small website or API on one server. It helps you ask better questions; it is not a quote or a guarantee that a particular configuration will fit your workload. Start with the workload Write down the application and database you plan to run, the audience's locations, expected traffic, operating system, and who will maintain the server. Estimate the resources together: an API and its database running on the same machine share CPU, memory and disk. Leave room for logs, operating-system updates and growth; test your own application rather than assuming a generic configuration will be enough. Select a region to investiga...

WordPress staging on a separate server: a practical isolation checklist

A staging site lets you test WordPress changes before they reach a live site. A separate server can give testing its own compute resources, but the server alone does not isolate databases, customer data, email, or payment integrations. Check those connections before running tests. 1. Decide what needs to be separate List the production sites, databases, file storage, scheduled tasks, and third-party services involved. For staging, use a separate database and separate credentials. Verify that the staging configuration points to the staging database and storage before editing content or running a test. If browser tests create bursts of requests, measure the load and duration of a representative run. Consider whether those tests should share a server with live sites, where they may compete for resources, or run on a separate server. The right CPU, memory, and storage depend on the sites and tests; a fixed minimum is not a performance guarantee. 2. Limit access to the staging copy Use...

Before choosing a second cloud provider: a practical recovery checklist

  UCELI provides cloud servers and domain services. This educational article was prepared with AI assistance. It does not describe a managed disaster recovery service or guarantee that UCELI backups are available or recoverable. A second cloud account can give you another place to run an application. It does not automatically give you a recovery plan. Both environments might depend on the same DNS provider, identity system or encryption key. A database copy might be out of date, and changing DNS does not stop the original server from accepting writes. Before comparing server prices, map the dependencies and rehearse a recovery using test data. These checks are for infrastructure you own or are authorized to test. They are not a guarantee of failover or zero data loss. 1. Define what must recover Choose one workload and write down two targets: Recovery time objective (RTO): the maximum interruption the business intends to tolerate. Recovery point objective (RPO): the maximum ...
